Since 5f8e93c3e2 ("util/qemu-timer: Make timer_free() imply timer_del()",
2021-01-08)
it is not possible anymore to pass a NULL pointer to timer_free(). Previously
it would do nothing as it would simply pass NULL down to g_free().
Rectify this, which also fixes "-chardev braille" when there is no device.
