[PATCH] RDMA: remove useless condition in siw_create_cq()

From: Andrey Strachuk
Date: Mon Jul 11 2022 - 11:13:04 EST


Comparison of 'cq' with NULL is useless since
'cq' is a result of container_of and cannot be NULL
in any reasonable scenario.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
