Subject: [PATCH 1/2] libhns: Remove unnecessary QP checks

mainline inclusion
from mainline-v47.0
commit 4ea9a4f77ac8c174d1ae4cf551a2e5abea13516f
category: cleanup
bugzilla: https://gitee.com/src-openeuler/rdma-core/issues/I7NT3M
CVE: NA

Reference: https://github.com/linux-rdma/rdma-core/commit/4ea9a4f77ac8c174d1ae4cf551a2e5abea13516f

----------------------------------------------------------------------

It is not necessary to check the type of the queue on post_send and
post_recv since the QP type that cannot be supported will be rejected
when it is created.

Check for srq in post_recv has also been removed, because the RQ of
QP bound to srq is empty and will return immediate error in post_recv.

Besides, remove the unused parameter ctx.
