Subject: RDMA: remove useless condition in siw_create_cq()
Patch-mainline: v6.0-rc1
Git-commit: aeea6cc067525103301fb7a6ba5c861b631f2086
References: jsc#PED-1503

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.

Fixes: 303ae1cdfdf7 ("rdma/siw: application interface")
