parse_unit_factor() multiplies the number that is passed to it with the
value of a recognized unit factor (K, M or G for 2^10, 2^20 and 2^30,
respectively). All callers pass in 1 as a number, though, which allows
them to check the actual multiplication for overflow before they are
doing it themselves.
Ignore the passed in number and don't multiply, as this feature of
parse_unit_factor() is not used anymore. Rename the output parameter to
reflect that it's not about the end result anymore, but just about the
unit factor.
