hvcs: Use vhangup in hotplug remove
When hotplug removing an hvcs device, we need to ensure the
hangup processing is done prior to exiting the remove function,
so use tty_vhangup to do the hangup processing directly
rather than using tty_hangup which simply schedules the hangup
work for later execution.
