[GIT PULL] Btrfs fixes for 5.11-rc5

[David Sterba <dsterba@suse.com>]

Hi,

a few more one line fixes for various bugs, stable material.

- fix send when emitting clone operation from the same file and root

- fix double free on error when cleaning backrefs

- lockdep fix during relocation

- handle potential error during reloc when starting transaction

- skip running delayed refs during commit (leftover from code removal in
  this dev cycle)

Please pull thanks.
