handle unaligned data in xfs_bmbt_disk_get_all

In libxfs xfs_bmbt_disk_get_all needs to handle unaligned data and thus has been updated to use get_unaligned_be64. In kernelspace we don't strictly need it as the routine is only used for tracing and xfsidbg, but let's keep the two implementations in sync.
