xfsdump: Revert "xfsdump: handle bind mount targets"

Bind mount mntpnts will be forbided in the next commits
instead since it's not the real rootdir.

This cannot be reverted cleanly due to several cleanup
patches, but the logic is reverted equivalently.

This reverts commit 25195ebf107dc81b1b7cea1476764950e1d6cc9d.
