In uipc_usrreq(PRU_ACCEPT), grab the unp_streamlock before unp_setpeerlocks().
This fixes a race where, for a short period of time, so->so_lock and
so2->so_lock are not sync. This makes solocked2() and solocked()
unreliable and cause DIAGNOSTIC kernel panics. This also fixes a possible
panic in unp_setaddr() which expects the socket locked.
Should fix kern/38968, fix proposed in
