Btrfs fixes for 7.0-rc6

Hi,

please pull a few more fixes. There's one that stands out in size as it fixes an edge case in fsync. Thanks.

- fix issue on fsync where file with zero size appears as a non-zero after log replay

- in zlib compression, handle a crash when data alignment causes folio reference issues

- fix possible crash with enabled tracepoints on a overlayfs mount

- handle device stats update error

- on zoned filesystems, fix kobject leak on sub-block groups

- fix super block offset in an error message in validation
