winverbs/winmad: check return value of DeviceIoControl

We need to check the return value
from DeviceIoControl before
calling GetOverlappedResult to avoid potential hangs.

[IPoIB]
DHCP fix (Linux-Windows interop). The patch caused by the change at Client
Identifier (CID) format:
 The format of Client Identifier Field (CID) was changed.

/* The CID will contain of:

 CID[0] = DHCP_OPT_CLIENT_ID == 61

 CID[1] = coIPoIB_CID_Len == 22

 CID[2:13] = coIBDefaultDHCPPrefix; (Here CID[2] always == coIPoIB_HwTypeIB == 0xFF)

 CID[14:21] = GUID;

Message:
[MLX4] Fix ioremap to use consistent caching attribute

When mapping Blue Flame registers to user-mode,
the UAR page is first mapped from I/O space to kernel-mode, then from kernel-mode to user-mode.
The mapping from I/O space uses the function ioremap, which is hard coded to use MmNonCached as
the caching attribute.  The subsequent mapping to user-mode specifies MmWriteCombined.
On Windows Server 2008 R2, the memory manager catches the inconsistency and preserves the
original MmNonCached attribute.  This leads to a 200-400% regression in small message latencies
due to not write combining when writing the request to the blue flame register.

The following patch
adds a caching type as a parameter to ioremap, changes all previous callers to specify MmNonCached
except in __map_memory_for_user, which already took a caching type, in which case it forwards the
caching type to ioremap.

With this patch, small message latency is identical on Windows Server 2008
and Windows Server 2008 R2.

     Memory leaks fixed.

   OFED Installer

     For 64-bit architectures, 32-bit .dll versions are installed into %windir%\SysWow64\

**** Known Issues ****

HCA drivers are reclassified as BOOT_START drivers to support booting from
an SRP IOC.  An unfortunate side-effect is when OFED 2.3 is installed
on a system for the first time, after installation a mandatory reboot is
Required by Windows.

After the OFED.msi file has started installation, an errant
"Welcome to the Found New Hardware Wizard" window 'may' popup; XP & Svr 2003.

Just ignore or 'cancel' the errant FNHW popup window in order to proceed with
the installation. XP requires a cancel, for WLH & WNET, the notifier will
disappear on their own.

You do need to answer 'Yes' or 'Continue' to popup windows which refer to
Non-Logo'ed (aka, Non-WHQL'ed) drivers being installed.

If the install appears to hang, look around for popup windows requesting input
which are covered by other windows.
Such is the case on Server 2008 initial install - Answer 'yes' to always trust
the OpenFabrics Alliance as a SW publisher.

Please:
  Read the Release_notes.htm file!

  make 'sure' your HCA firmware is recent:
      vstat.exe displays HCA firmware version & PSID.
      flint.exe (found in the Mellanox firmware tools package) displays PSID.

Thank you,

OFED for Windows developers.
