RDMA/irdma: Remove a NOP wait_event() in irdma_modify_qp_roce()

Remove a NOP wait_event() in irdma_modify_qp_roce() which is relevant
for iWARP and likely a copy and paste artifact for RoCEv2. The wait event
is for sending a reset on a TCP connection, after the reset has been
requested in irdma_modify_qp(), which occurs only in iWarp mode.
