Subject: [PATCH] mi: force the paired kbd device before CopyKeyClass. (#19574)

Some multi-media keyboards send the key events for multimedia keys through the
device file used by the mouse. Sending a key event through the VCP however
will fail. The VCP doesn't have a key class so the server crashes or (with an
appropriate fix) the event is simply swallowed.

Thus, for key events if the master does not have a key class, get the device
paired with the master (i.e. the VCK) before processing the event any further.
