xfs: fix incorrect unit conversion in scrub tracepoint
XFS_DADDR_TO_FSB converts a raw disk address (in units of 512b blocks)
to a raw disk address (in units of fs blocks). Unfortunately, the
xchk_block_error_class tracepoints incorrectly uses this to decode
xfs_daddr_t into segmented AG number and AG block addresses. Use the
correct translation code.
