In this third iteration of the patches some issues were fixed. Special thanks to
Qu that raised some questions about bind mounts and subvolumes not mounted. The
first test didn't change.

Changes from v2:
* Make mnt_opts check more strict to avoid bind mounts (Qu)
* Print only inode/subvolume when the subvolume itself is not mounted
* Enhance the test by adding a snapshot (unmounted) to exercise the check above
* Enhance the test by adding a bind mount that would trick logical-resolve

Changes from v1:
* Patches 2 and 3 added
* Test created (David)
* Discard changed on btrfs_list_path_for_root and changing find_mount_root
  instead
