[PATCH] RDMA/cxgb4: Fix memory leaks in c4iw_alloc() error paths

[Christoph Jaeger <christophjaeger@linux.com>]

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")
