[GIT PULL] Btrfs fixes for 7.3-rc4

[David Sterba <dsterba@suse.com>]

Hi,

please pull the following fixes. Among the regular fixes, there are two
that were reported recently and have user impact:

- filesystem id is now stable again on the default and common case (it
  broke openconnect key derivation, while this is not secure, it's still
  in use), the intention was to change id for the temp_fsid use case

- fix detection of /dev/root and rename it after device scan, this broke
  booting of initramdisk-less system with grub2 as the probe needs the
  real device

Regular fixes:

- don't store compressed inline extent if the size is larger than
  uncompressed

- in zoned mode, handle activation of zones for all supported block
  group profiles in case there are still free ones left

- check space for a chunk item when reading sys array from superblock

- allow using space reserves when removing verity items fails

- fix error handling after free space tree rebuild fails

- abort transaction if reflink or hole punching fails and it's not
  possible to update the inode

- properly protect block group iteration during device replace start

- error message fixups
