Zongmin Zhou c853246539 Input: vmmouse - disable vmmouse before entering suspend mode
Currently, when trying to suspend and resume with VirtualPS/2 VMMouse
there is an error message after resuming:

	psmouse serio1: vmmouse: Unable to re-enable mouse when reconnecting, err: -6

and the mouse will no longer be operable, requiring full rescan to find a
another driver to use for the port.

This error is due to QEMU still generating PS2 events which the kernel is
not consuming until resume time, where they interfere with mouse
identification and ultimately resulting in an error getting
VMMOUSE_VERSION_ID.

Test scenario:

1) start virtual machine with qemu command "vmport=on"
2) click suspend botton to enter suspend mode
3) resume and observe the error message in the kernel logs

Let's fix this by disabling the vmmouse in its reset handler. This will
notify qemu to stop vmmouse and remove the handler.
