ipa: rkisp1: algorithms: awb: Check for correct stats type

Sometimes the ISP produces statistics only with a subset of statistic
types being valid. It doesn't happen normally, but was observed in the
wild. Check for the RKISP1_CIF_ISP_STAT_AWB bit to prevent using invalid
or outdated data. As it doesn't happen regularly add an error message to
get notified when it happens.

For simpler code structure, the ColourTemperature metadata entry gets
written unconditionally and overwritten later if needed.
