[ewg] suggested fix in iscsi RHEL backport

[Michael S. Tsirkin]

Hi!
I noticed that RHEL backports include a copy of include/scsi/iscsi_proto.h from
upstream kernel which is a large file, so carrying it around is a maintainance
problem going forward.  Since this header includes protocol definitions, I think
we should check it out from upstream, always.

Code for such a change can be found here:
git.openfabrics.org/~mst/ofed_1_2_devel.git ofed_1_2

Erez, do you agree?
Can you take a look and comment whether we can include this in OFED 1.2?
