[PATCH xf86-video-qxl 1/4 v2] Add and remove the vdagent interface as the vdagent actually connects and disconnects.

[Jeremy White <jwhite@xxxxxxxxxxxxxxx>]

This means that we do not attempt to use agent mouse
mode if there is no connected agent.

It fixes a bug which would occur if an agent disconnected
after session startup which would result in having no
useful mouse.
