In cm_req_handler(), unify the check for RoCE and re-factor to avoid
one test.
Suggested-by: Jason Gunthorpe <jgg@nvidia.com>
Fixes: 8f9748602491 ("IB/cm: Reduce dependency on gid attribute ndev check")
Fixes: 194f64a3cad3 ("RDMA/core: Fix corrupted SL on passive side")

I think your other note was right, the gid_attr cannot be NULL when in
ROCE mode, so we can delete the 'gid_attr &&' term too

Well, I marked it as changes-requested so I guess I did..
But anyway I'll fix it up, it does look obviously correct
