accessibility: speakup: unregister tty ldisc on later init failures
commit a76acbaec9b8fd74413646984d2e3626d0543e39 upstream.
The ldisc registration is intentionally non-fatal, since some synth
drivers do not use tty/ldisc. However, once speakup_init() continues
past the registration point and later fails, the init unwind path should
mirror speakup_exit() and call spk_ttyio_unregister_ldisc().
Add the missing unregister call to the error path after synth_release(),
matching the normal module exit cleanup order.
