If log stripe unit isn't a multiple of the fs blocksize and mounting,
the invalid sb_logsunit leads to crash as soon as we try to write to
the log.

_scratch_xfs_get_metadata_field ?

(Or, _scratch_xfs_get_sb_field if Hou Tao's dquot unmount tests go in)

_scratch_xfs_set_metadata_field ?

Otherwise this looks decent.

Agreed.  Use _scratch_xfs_get_sb_field here.
