xfs: fix sparse reported log CRC endian issue
Not a bug as such, just warning noise from the xlog_cksum() returning a __be32 type when it should be returning a __le32 type.

So rather than always having to byte swap it everywhere and have all the force casts and anootations for sparse, it seems simpler to just make it a __le32 everywhere....
