As per IBTA specification, all subsequent WQEs while QP is in error state
should be completed with a flush error.
Here we check QP_STATE_ERROR after req_next_wqe() so that rxe_completer()
has chance to be called where it will set CQ state to FLUSH ERROR and the
completion can associate with its WQE.
