[pve-devel] Fix tablet as default pointer after live migration

[Derumier Alexandre]

They are a bug in qemu > 1.0, when we live migrate a vm,
tablet usb device is not set as default mouse.

before migration

# info mice
  Mouse #0: QEMU PS/2 Mouse
* Mouse #1: QEMU HID Tablet (absolute)

after live migrate

# info mice
  Mouse #1: QEMU HID Tablet (absolute)
* Mouse #0: QEMU PS/2 Mouse

This patch send "mouse_set 1" at vm start.

I have tested it, it's works without bug. User report it's working fine too.
