Darrick J. Wong 0c9ec4beec ext4: support GETFSMAP ioctls ...

Support the GETFSMAP ioctls so that we can use the xfs free space
management tools to probe ext4 as well.  Note that this is a partial
implementation -- we only report fixed-location metadata and free space;
everything else is reported as "unknown".
