sched/fair: Fix group power_orig computation
When looking at the code I noticed we don't actually compute sgp->power_orig correctly for groups, fix that. Currently the only consumer of that value is fix_small_capacity() which is only used on POWER7+ and that code excludes this case by being limited to SD_SHARE_CPUPOWER which is only ever set on the SMT domain which must be the lowest domain and this has singleton groups. So nothing should be affected by this change.
