Add hid_has_events function, use it to figure whenever there are pending events instead of checking and updating USBHIDState->changed. Setting ->changed to 1 on init is removed, that should have absolutely no effect as the initial state of ->idle is 0 so we report hid state anyway until the guest configures some idle time. Also should clear ->idle on reset. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
