Maksim Davydov fc0c128531 chardev: fix segfault in finalize ...

If finalize chardev-msmouse or chardev-wctable is called immediately after
init it cases QEMU to crash with segfault. This happens because of
QTAILQ_REMOVE in qemu_input_handler_unregister tries to dereference
NULL pointer.
For instance, this error can be reproduced via `qom-list-properties`
command.
