sched/fair: Remove unused but set variable 'rq'
Since commit:
8663e24d56dc ("sched/fair: Reorder cgroup creation code")
... the variable 'rq' in alloc_fair_sched_group() is set but no longer used.
Remove it to fix the following GCC warning when building with 'W=1':
kernel/sched/fair.c:8842:13: warning: variable ‘rq’ set but not used [-Wunused-but-set-variable]
