xfs: create helpers to convert rt block numbers to rt extent numbers
Create helpers to do unit conversions of rt block numbers to rt extent
numbers. There are three variations -- one to compute the rt extent
number from an rt block number; one to compute the offset of an rt block
within an rt extent; and one to extract both.
