Ordering of RGB is wrong in ncs-fullcheck.c

You have to transpose RGB to BGR before subtracting means.

@koichi Thanks for bringing this to our attention! We'll take a look.

@koichi This is indeed an issue in this sample. The next release will include the fix, and we're checking other samples as well.

Thanks again.
