virtio: console: Don't call hvc_remove() on unplugging console ports ...
hvc_remove() has some bug which freezes other active hvc ports when one
port is removed.
So disable calling of hvc_remove() which deregisters a port with the
hvc_console.
If the hvc_console code calls into our get_chars() routine as a result
of a poll operation, we will return -EPIPE and the hvc_console code will
then do the necessary cleanup.
This call will be restored when the bug in hvc_remove() is found and
fixed.
