Updates to the file system geometry in growfs need to be committed to stable store before the allocator can see them to avoid that they are in the same CIL checkpoint as transactions that make use of this new information, which will make recovery impossible or broken. To do this add two new helpers to prepare a superblock for direct manipulation of the on-disk buffer, and to commit these updates while holding the buffer locked (similar to what xfs_sync_sb_buf does) and use those in growfs instead of applying the changes through the deltas in the xfs_trans structure (which also happens to shrink the xfs_trans structure a fair bit). The rtbmimap repair code was also using the transaction deltas and is converted to also update the superblock buffer directly under the buffer lock. This new method establishes a locking protocol where even in-core superblock fields must only be updated with the superblock buffer locked. For now it is only applied to affected geometry fields, but in the future it would make sense to apply it universally.
