xfs: add CRC checking to dir2 free blocks
This addition follows the same pattern as the dir2 block CRCs, but with a few differences. The main difference is that the free block header is different between the v2 and v3 formats, so an "in-core" free block header has been added and _todisk/_from_disk functions used to abstract the differences in structure format from the code. This is similar to the on-disk superblock versus the in-core superblock setup. The in-core strucutre is populated when the buffer is read from disk, all the in memory checks and modifications are done on the in-core version of the structure which is written back to the buffer before the buffer is logged.
