v4l2src: failure to query some optional controls is not a fatal error
Don't post a (fatal) error message on the bus just because we failed to query some control. Fixes issue with built-in Suyin Corp webcam for HP notebook (usbid 064e:e28a) on OpenSuse 12.1, where querying red/blue balance fails. https://bugzilla.gnome.org/show_bug.cgi?id=670197
