xfs: add CRC checking to dir2 leaf blocks
This addition follows the same pattern as the dir2 block CRCs. Seeing as both LEAF1 and LEAFN types need to changed at the same time, this is a pretty large amount of change. leaf block headers need to be abstracted away from the on-disk structures (struct xfs_dir3_icleaf_hdr), as do the base leaf entry locations. This header abstract allows the in-core header and leaf entry location to be passed around instead of the leaf block itself. This saves a lot of converting individual variables from on-disk format to host format where they are used, so there's a good chance that the compiler will be able to produce much more optimal code as it's not having to byteswap variables all over the place.
