Subject: [PATCH] sched: Kill off dead cfs_rq_set_shares().

Building with CONFIG_FAIR_GROUP_SCHED=y on UP results in an unused
cfs_rq_set_shares() reference. As nothing is using this dummy function
in the first place, just kill it off.

Against current git, but still seems to be relevant to 'sched-devel' in
-tip.
