Input: appletouch - initialize work before device registration
commit 9f3ccdc3f6ef10084ceb3a47df0961bec6196fd0 upstream.
Syzbot has reported warning in __flush_work(). This warning is caused by
work->func == NULL, which means missing work initialization.
This may happen, since input_dev->close() calls
cancel_work_sync(&dev->work), but dev->work initalization happens _after_
input_register_device() call.
So this patch moves dev->work initialization before registering input
device
Fixes: 5a6eb676d3bc ("Input: appletouch - improve powersaving for Geyser3 devices")
