bluetooth: hci_ldisc: fix deadlock condition
commit da64c27d3c93ee9f89956b9de86c4127eb244494 upstream.
LDISCs shouldn't call tty->ops->write() from within
->write_wakeup().
->write_wakeup() is called with port lock taken and
IRQs disabled, tty->ops->write() will try to acquire
the same port lock and we will deadlock.
