[IB] umad: further ib_unregister_mad_agent() deadlock fixes The previous umad deadlock fix left ib_umad_kill_port() still vulnerable to deadlocking. This patch fixes that by downgrading our lock to a read lock when we might end up trying to reacquire the lock for reading. Signed-off-by: Roland Dreier <rolandd@cisco.com>
