[GIT PULL] Btrfs fixes for 6.8-rc5

[David Sterba]

Hi,

a few regular fixes and one fix for space reservation regression since
6.7 that users have been reporting.

Please pull, thanks.

- fix over-reservation of metadata chunks due to not keeping proper balance
  between global block reserve and delayed refs reserve;
  in practice this leaves behind empty metadata block groups, the workaround
  is to reclaim them by using the '-musage=1' balance filter

- other space reservation fixes:
  - do not delete unused block group if it may be used soon
  - do not reserve space for checksums for NOCOW files

- fix extent map assertion failure when writing out free space inode

- reject encoded write if inode has nodatasum flag set

- fix chunk map leak when loading block group zone info

----------------------------------------------------------------
The following changes since commit e03ee2fe873eb68c1f9ba5112fee70303ebf9dfb:

  btrfs: do not ASSERT() if the newly created subvolume already got read (2024-01-31 08:42:53 +0100)
