[PATCH] sched/rt: Fix -Wmissing-prototypes warnings

[Yi Wang]

We get a warning when building kernel with W=1:
kernel/sched/rt.c:626:6: warning: no previous prototype for 
‘sched_rt_bandwidth_account’ [-Wmissing-prototypes]
 bool sched_rt_bandwidth_account(struct rt_rq *rt_rq)

Add the missing declaration to fix this.
