Subject: RDMA/cxgb4: Fix memory leaks in c4iw_alloc() error paths
From: Christoph Jaeger <christophjaeger@xxxxxxxxx>
commit 65b302ad31b02b0790417f4e65833af494cb35ce upstream.
c4iw_alloc() bails out without freeing the storage that 'devp' points to.
Picked up by Coverity - CID 1204241.
Fixes: fa658a98a2 ("RDMA/cxgb4: Use the BAR2/WC path for kernel QPs and T5 devices")
