Subject: RDMA/bnxt_re: Fix static checker warning
Patch-mainline: v4.16-rc1
Git-commit: 589ccd8b0404281ebc84fe9a9ae51ddbc6d1a8c1
References: bsc#1104742 FATE#325917

If there is ever any error while creating srq->umem, we return that
error, we don't store it in srq->umem, so any check of srq->umem for
IS_ERR is pointless.  Further, checking udata is unnecessary as
srq->umem is always either NULL or valid, without respect to udata.
