RDMA/bnxt_re: Change the sequence of updating the CQ toggle value
Currently the CQ toggle value in the shared page (read by the userlib) is
updated as part of the cqn_handler. There is a potential race of
application calling the CQ ARM doorbell immediately and using the old
toggle value.
Change the sequence of updating CQ toggle value to update in the
bnxt_qplib_service_nq function immediately after reading the toggle value
to be in sync with the HW updated value.
