IB/qib: Process RDMA WRITE ONLY with IMMEDIATE properly

Browse source

See table 35 in IBA - the header order for RDMA_WRITE_ONLY_WITH_IMMEDIATE
and SEND_LAST_WITH_IMMEDIATE is different: the RDMA_WRITE_ONLY has
a RETH header before the immediate data, so we need a different code path
to extract the immediate data.

I tested this with a userspace app that does RDMA_WRITE with immediate
on a QLE7140.
