From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The null check on a failed workqueue create is currently null checking
hdev->cq_wq rather than the pointer hdev->cq_wq[i] and so the test
will never be true on a failed workqueue create. Fix this by checking
hdev->cq_wq[i].
Addresses-Coverity: ("Dereference before null check")
Fixes: 5574cb2194b1 ("habanalabs: Assign each CQ with its own work queue")
