Before the testing, we already passed it to rxe_mr_copy() where mr could
be dereferenced. so this checking is not needed.

The only way that mr is NULL is when it reaches below line 780 with
 'qp->resp.mr = NULL', which is not possible in Bob's explanation[1].

 778         if (res->state == rdatm_res_state_new) {
 779                 if (!res->replay) {
 780                         mr = qp->resp.mr;
 781                         qp->resp.mr = NULL;
 782                 } else {

rxe_recheck_mr() will increase mr's ref_cnt, so we should call rxe_put(mr)
to drop mr's ref_cnt in RESPST_ERR_RNR to avoid below warning:

This is correct. Good catch. Needs cleanup per Leon otherwise it's good.

Sigh, please try to avoid sending patches in a way that causes
patchworks to become confused. I updated things to remove the if as in
this v2.
