btrfs: incremental send after renaming a file and a directory

Test that an incremental send works if we rename some directory inode A
and then rename some file inode B to the name inode A had, for the case
where the directory inode A is an ancestor of inode B in the parent
snapshot.

This issue is fixed by the following patch for the linux kernel:

  "Btrfs: incremental send, fix invalid path for unlink commands"
