[BRIDGE]: Fix device delete race.
This is a simpler fix for the two races in bridge device removal. The Xen race of delif and notify is managed now by a new deleted flag. No need for barriers or other locking because of rtnl mutex. The del_timer_sync()'s are unnecessary, because br_stp_disable_port delete's the timers, and they will finish running before RCU callback.
