[AF_UNIX]: Make socket locking much less confusing.
The unix_state_*() locking macros imply that there is some rwlock kind of thing going on, but the implementation is actually a spinlock which makes the code more confusing than it needs to be. So use plain unix_state_lock and unix_state_unlock. Signed-off-by: David S. Miller <davem@davemloft.net>
