[PATCH 4/8] xfsprogs: mkfs.xfs: let libxfs_umount() do its thing

From: Kevan Rehm <kfr@sgi.com>

In the mkfs.xfs main() routine (which is gargantuan, by the way),
there are a few function calls intended to do some clean up before
unmounting the filesystem.

The first function drops references that will be dropped again in
the unmnount call. The others assume all references will go away as
a result of the purge, but the filesystem's root inode reference
will remain.

Let the unmount function take care of destroying the real-time
structures. And instead of purging the inode and block caches, just
flush them (at least the block cache) and let the unmount code take
care of the final purge.
