Simplify the available scales building.

Building the available scales tables looks confusing. It has also been a
source of a few memory leaks.

Attempt making it a bit less error prone by simplifying some error paths
using __free(kfree) from the cleanup.h. Try doing this without
introducing variables in the middle of a function while also improving
the logic of the functions. This is possble by splitting the long scale
building logic in a couple of different, well purposed functions, and
finally streamlining the logic a bit by taking out one extra 'total gains
to scales'-conversion.

Inspired by the discussion here:
