Revert "Avoid ELOOP on auto-mounted snapshots"

Browse Source 
This reverts commit 7afcf5b1da which
accidentally introduced a regression with the .zfs snapshot directory.
While the updated code still does correctly mount the requested
snapshot.  It updates the vfsmount such that it references the
original dataset vfsmount.  The result is that the snapshot itself
isn't visible.
