RDMA/rxe: Fix "Replace mr by rkey in responder resources"
The referenced commit generates a reference counting error if the rkey has
the same index but the wrong key. In this case the reference taken by
rxe_pool_get_index() is not dropped.
Drop the reference if the keys don't match in rxe_recheck_mr(). Check
that the mw and mr are still valid.
