[GIT PULL] Btrfs fixes for 7.4-rc3

[David Sterba]

Hi,

please pull a few fixes. Thanks.

- zoned mode fixes
  - fix counting active zones after activation
  - redo zone reset after error
  - update device lock range during mount and zone loading to avoid lockdep
    warnings with device drivers (virtio)
  - space accounting and extent buffer handling fixes

- fix keeping zstd workspace for the last level

- in SUBVOL_SYNC ioctl handle a real case of a subvolume with 0 refs

- properly handle case of zero num_stripes when reading chunk items

- exclude reloc tree from xarray as it's special and it's key does not fit
  unsigned long on 32bit platforms

- in tree-checker, handle extent item tree owner depending on the features
  (enabled in simple quota mode)

- fix bio control structure leak when checksumming fails
