From: Robbie Ko <robbieko@xxxxxxxxxxxx>
Test that an incremental send operation dosen't work because
it tries to rename a directory which is already deleted.
This test exercises scenarios used to fail in btrfs and are fixed by
the following patch for the linux kernel:
"Btrfs: incremental send, add generation check for inode is waiting for move."
