Btrfs fixes for 7.4-rc2

Hi,

please pull a few btrfs fixes. The ones that could have some user noticeable impact are enumerated, the rest is one-liners.

Please pull, thanks.

- fix chattr failing on files with nodatasum and compress flags

- fix inode defrag status with concurrent truncation so it's not skipped in defrag in the future

- fix merging compressed extent in fiemap output

- fix deleting wrong subvolume by id if it gets renamed during the ioctl

- error handling fixes: sysfs, quotas, fs-verity, scrub, zoned mode
