[PATCH 1/6] xfs: recalculate summary counters at mount time if icount is bad

["Darrick J. Wong" <darrick.wong@xxxxxxxxxx>]

From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>

Since the sb write verifier trips on bad icounts, we should also force a
mount time recalculation of the summary counters if the icount is bad.
This helps us avoid blowing up at freeze/unmount time when the bad
counter gets written back out.
