Always acquire the UNIX domain socket subsystem lock (UNP lock)
before dereferencing sotounpcb() and checking its value, as so_pcb
is protected by protocol locking, not subsystem locking.  This
prevents races during close() by one thread and use of ths socket
in another.

unp_bind() now assert the UNP lock, and uipc_bind() now acquires
the lock around calls to unp_bind().
