goodixmoc: Report recognized print after a match failure

Browse Source 
The API should return the recognized print, even if none of the prints
given in the gallery (or the one passed to verify) matched. Without this
the garbage-collection of left-over prints does not work, causing issues
after reinstall.

Fixes: #444
