tty_ldisc: Fix BUG() on hangup
commit 1c95ba1e1de7edffc0c4e275e147f1a9eb1f81ae upstream.
A kernel BUG when bluetooth rfcomm connection drop while the associated
serial port is open is sometime triggered.
It seems that the line discipline can disappear between the
tty_ldisc_put and tty_ldisc_get. This patch fall back to the N_TTY line
discipline if the previous discipline is not available anymore.
