[PATCH v1 1/2] ui/vdagent: call vdagent_disconnect() when agent connection is lost

[tugy]

From: Guoyi Tu <t...@chinatelecom.cn>

when the agent connection is lost, the input handler of the mouse
doesn't deactivate, which results in unresponsive mouse events in
VNC windows.

To fix this issue, call vdagent_disconnect() to reset the state
each time the frontend disconncect
