[GIT PULL] Btrfs fixes for 5.3-rc5

[David Sterba]

Hi,

please pull two fixes that pop during testing:

* fix for sysfs-related code that adds/removes block groups, warnings
  appear during several fstests in connection with sysfs updates in 5.3,
  the fix essentially replaces a workaround with scope NOFS and applies
  to 5.2-based branch too

* add sanity check of trim range

Thanks.
