Oliver Neukum eff73de2b1 media: cpia2_usb: first wake up, then free in disconnect 
Kasan reported a use after free in cpia2_usb_disconnect()
It first freed everything and then woke up those waiting.
The reverse order is correct.

Fixes: 6c493f8b28 ("[media] cpia2: major overhaul to get it in a working state again")
