cluster/distribute: re-set layouts to prevent overlaps
When subvols-per-directory option is used, with bricks addition/removal
the layouts might get distributed to other subvols, which were not part
of the layout before. We need to clean up layouts on old subvolumes, to
prevent overlaps.
Also, we need to make sure if layout-cnt is never less
than subvolume-cnt.
