Jiri Kosina 4bf3631cdb 8250: fix possible deadlock between serial8250_handle_port() and serial8250_interrupt() 
Commit 40b36daa introduced possibility that serial8250_backup_timeout() ->
serial8250_handle_port() locks port.lock without disabling irqs, thus
allowing deadlock against interrupt handler (port.lock is acquired in
serial8250_interrupt()).

Spotted by lockdep.
