Ameer Hamza a5ba57ad82 Validate mountpoint on path-based unmount using statx
Use statx to verify that path-based unmounts proceed only if the
mountpoint reported by statx matches the MNTTAB entry reported by
libzfs, aborting the operation if they differ. Align
`zfs umount /path` behavior with `zfs umount dataset`.
