Darrick J. Wong 2fd273886b xfs: refactor minimum log size formatting code
Create a new helper function to discover the minimum log size that will
work with the mkfs options provided, then remove all the hardcoded block
sizes from various xfs tests.  This will be necessary when we turn on
reflink or rmap by default and the minimum log size increases.
