HID: magicmouse: fix NULL-deref on disconnect

Commit 9d7b18668956 (“HID: magicmouse: add support for Apple Magic
Trackpad 2”) added a sanity check for an Apple trackpad but returned
success instead of -ENODEV when the check failed. This means that the
remove callback will dereference the never-initialised driver data
pointer when the driver is later unbound (e.g. on USB disconnect).
