RDMA/rxe: let rxe_reclassify_recv_socket() call sk_owner_put()

RDMA/rxe: let rxe_reclassify_recv_socket() call sk_owner_put()

On kernels build with CONFIG_PROVE_LOCKING, CONFIG_MODULES
and CONFIG_DEBUG_LOCK_ALLOC 'rmmod rdma_rxe' is no longer
possible.

For the global recv sockets rxe_net_exit() is where we
call rxe_release_udp_tunnel-> udp_tunnel_sock_release(),
which means the sockets are destroyed before 'rmmod rdma_rxe'
finishes, so there's no need to protect against
rxe_recv_slock_key and rxe_recv_sk_key disappearing
while the sockets are still alive.
