[PATCH rdma-next 2/4] RDMA/bnxt_re: Remove unnecessary checks in kernel CQ creation path

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@nvidia.com>

bnxt_re_create_cq() is a kernel verb, which means udata will always be
NULL and attr->cqe is valid. Remove the code handling this unreachable
case.
