Johan Hovold bbd5d7adde staging: speakup: fix tty-operation NULL derefs ...

commit a1960e0f16 upstream.

The send_xchar() and tiocmset() tty operations are optional. Add the
missing sanity checks to prevent user-space triggerable NULL-pointer
dereferences.

Fixes: 6b9ad1c742 ("staging: speakup: add send_xchar, tiocmset and input functionality for tty")
