RDMA/rvt: Return NULL after port allocation failure
rvt_alloc_device() deallocates the IB device when its port array cannot
be allocated but then returns the pointer to the released allocation.
Callers treat any non-NULL value as valid and dereference it, resulting
in a use-after-free.
Return NULL immediately after deallocation so callers can propagate the
allocation failure.
Fixes: ff6acd69518e ("IB/rdmavt: Add device structure allocation")
