usb/hid: add hid_pointer_activate, use it
HID reorganziation broke the usb tablet in windows xp. The reason is
that xp activates idle before it starts polling, which creates a
chicken-and-egg issue: We don't call hid_pointer_poll because there are
no pending events. We don't get any events because the activation code
in hid_pointer_poll is never executed and thus all pointer events are
routed to the PS/2 mouse by qemu.
Fix this by creating a hid_pointer_activate function and call it from
usb-hid when the guest sets the idle state.
