HID: magicmouse: Fix an error handling path in magicmouse_probe()
commit 33812fc7c8d77a43b7e2bf36a0d5a57c277a4b0c upstream.
If the timer introduced by the commit below is started, then it must be
deleted in the error handling of the probe. Otherwise it would trigger
once the driver is no more.
Fixes: 0b91b4e4dae6 ("HID: magicmouse: Report battery level over USB")
