crush: return CRUSH_ITEM_UNDEF for failed placements with indep
For firstn mode, if we fail to make a valid placement choice, we just continue and return a short result to the caller. For indep mode, however, we need to make the position stable, and return an undefined value on failed placements to avoid shifting later results to the left.
