[ofw] svn.2066 - trunk/hw/mlx4/kernel/hca/wmi.c fails to build

[Smith, Stan]

Hello Leo,
  When attempting to build svn.2066 I encountered the following mlx4 build error.

Duplicate definition for 'offsetof' error.

I found an example of this style of fix in the core\al folder and applied it to 'wmi.c'.
Mlx4 driver now builds.

Perhaps we should consider using the MS definition for 'offsetof' instead of our own?
