[GIT PULL] Btrfs fix for 5.11-rc8

[David Sterba]

Hi,

a regression fix caused by a refactoring in 5.11. A corrupted superblock
wouldn't be detected by checksum verification due to wrongly placed
initialization of the checksum length, thus making memcmp always work.

I've verified it manually and ran other test suites before sending this.
Please pull, thanks.
