[PATCH 03/10] xfs_db: support the needsrepair feature flag in the version command

["Darrick J. Wong" <djwong@xxxxxxxxxx>]

From: Darrick J. Wong <djwong@xxxxxxxxxx>

Teach the xfs_db version command about the 'needsrepair' flag, which can
be used to force the system administrator to repair the filesystem with
xfs_repair.
