ipa: raspberrypi: awb: Delay release of the statistics buffer

Browse source 
Release the statistics buffer after running the through the AWB calculations.
Only the "counted" statistics are copied out to a local structure, so keeping
the statistics buffer allows the algorithm to see the "uncounted" statistics as
well.

This is currently handled by hard-coding the total number of statistics regions
regions based on the structure definition in the bcm2835_isp_stats structure.
