Tomasz Pakuła d1edc027a4 HID: pidff: Fix condition effect bit clearing 
commit 97d5c8f5c0 upstream.

As reported by MPDarkGuy on discord, NULL pointer dereferences were
happening because not all the conditional effects bits were cleared.

Properly clear all conditional effect bits from ffbit

Fixes: 7f3d7bc0df ("HID: pidff: Better quirk assigment when searching for fields")
