Haoxiang Li 9ca3aab082 accessibility: speakup: unregister tty ldisc on later init failures 
commit a76acbaec9 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.
