Btrfs fixes for 7.1-rc5

Hi,

please pull a batch of fixes to simple quotas and one fix to inode size handling. Thanks.

- simple quota fixes:
- add conditional rescheduling point not dependent on the lock during inode iterations to avoid delays with PREEMPT_NONE enabled
- fix subvolume deletion so it does not break the squota invariants
- properly handle enabling squota, tracking extents in the initial transaction
- catch and warn about underflows, clamp to zero to avoid further problems

- fix handling of preallocated extents beyond i_size when not using the no-holes feature
