HID: magicmouse: fix crash when disconnecting Magic Trackpad 2
When the Apple Magic Trackpad 2 is connected over USB it registers four
hid_device report descriptors, however, the driver only handles the one
with type HID_TYPE_USBMOUSE and ignores the other three, thus, no driver
data is attached to them.
When the device is disconnected, the remove callback is called for the
four hid_device report descriptors, crashing when the driver data is
NULL.
Check that the driver data is not NULL before using it in the remove
callback.
