RDMA/qedr: SRQ's bug fixes
QP's with the same SRQ, working on different CQs and running in parallel
on different CPUs could lead to a race when maintaining the SRQ consumer
count, and leads to FW running out of SRQs. Update the consumer
atomically. Make sure the wqe_prod is updated after the sge_prod due to
FW requirements.
