btrfs: simplify percent calculation helpers, rename div_factor
The div_factor* helpers calculate fraction or percentage fraction. The
name is a bit confusing, we use it only for percentage calculations and
there are two helpers.
There's a helper mult_frac that's for general fractions, that tries to
be accurate but we multiply and divide by small numbers so we can use
the div_u64 helper.
Rename the div_factor* helpers and use 1..100 percentage range, also drop
the case checking for percentage == 100, it's never hit.
The conversions:
* div_factor calculates tenths and the numbers need to be adjusted
* div_factor_fine is direct replacement
