RDMA/rvt: Fix potential memory leak caused by rvt_alloc_rq

Browse source 
[ Upstream commit 90a239ee25fa3a483facec3de7c144361a3d3a51 ]

In case of failure of alloc_ud_wq_attr(), the memory allocated by
rvt_alloc_rq() is not freed. Fix it by calling rvt_free_rq() using the
existing clean-up code.

Fixes: d310c4bf8a ("IB/{rdmavt, hfi1, qib}: Remove AH refcount for UD QPs")
