USB Storage: Remove the finecam3 unusual_devs entry

This patch removes the Kyocera Finecam L3 entry in unusual devices
originally submitted by Michael Krauth <michael.krauth@web.de> and
Alessandro Fracchetti <al.fracchetti@tin.it> given that Gerriet
<ger.haw@gmx.de> finds he doesn't need it and Alessandro confirms it
isn't needed anymore as well.
