[PATCH] baum: Fix crash when Braille output is not available |

When Braille output is not available, the backend properly reports being
unable to be created, but 5f8e93c3e262 ("util/qemu-timer: Make timer_free()
imply timer_del()") made the timer_free() call now refuse any NULL
parameter. char_braille_finalize thus now has to be more careful with
calling it on baum->cellCount_timer.
