In commit
ac1b84dd1 (rhbz#
1027181), a check was added to only update the
"read handler" when the front-end is opened, because the read callbacks
were not restored when a device is plugged. However, this seems not
correct, the handler is correctly set back on hotplug (in
virtconsole_realize) and the bug can no longer be reproduced.
Calling chr_update_read_handler() allows to fix the mux driver to stop
calling the child handlers (which may be going to be destroyed).
