HID: fix processing of event quirks
The old code (before move) stopped further processing of the
event after it has been already processed by the quirk handler.
The new code didn't propagate the return value properly, and
therefore the processing always proceeded, which was wrong.
This patch fixes it. Pointed out in kernel.org bugzilla #9842
