[ewg] NFS/RDMA backport for OFED 4.8-1 part 3

[David Z. Dai]

Hi, Jeff:
It has the same error when loading "rpmcrdma" directly.
[root at rhel73_host1_guest1_local_htx modules]# modprobe rpcrdma
modprobe: ERROR: could not insert 'rpcrdma': Exec format error

I also change the "rpcrdma.ko" mode from 644 to 744. It still has the
same issue.

Thanks! - David Dai
