[GIT PULL] Btrfs fixes for 5.2-rc3

[David Sterba <dsterba@suse.com>]

Hi,

a few more fixes for bugs reported by users, fuzzing tools and
regressions:

* fix crashes in relocation
  * resuming interrupted balance operation does not properly clean up
    orphan trees
  * with enabled qgroups, resuming needs to be more careful about
    block groups due to limited context when updating qgroups

* fsync and logging fixes found by fuzzing

* incremental send fixes for no-holes and clone

* fix spin lock type used in timer function for zstd

No merge conflicts, please pull. Thanks.
