sched/fair: Hide unused init_cfs_bandwidth() stub

init_cfs_bandwidth() is only used when CONFIG_FAIR_GROUP_SCHED is
enabled, and without this causes a W=1 warning for the missing prototype:

kernel/sched/fair.c:6131:6: error: no previous prototype for 'init_cfs_bandwidth'

The normal implementation is only defined for CONFIG_CFS_BANDWIDTH,
so the stub exists when CFS_BANDWIDTH is disabled but FAIR_GROUP_SCHED
is enabled.
