cluster/distribute: get_layout should account only available subvolsv3.4.0qa7
The earlier logic used to check if (layout-spread-count <= subvol_cnt -
decommissioned bricks). With this if a subvol was down, and layout-spread was >
upsubvols, a mkdir ended up creating holes in the layout.
The fix is to consider only the combination of subvols which are usable (not
down or not decommissioned).
