[PATCH] sched/rt: Remove unnecessary CONFIG_RT_GROUP_SCHED in rt_se_prio()

[Muchun Song]

When CONFIG_RT_GROUP_SCHED is not configured, group_rt_rq() will
return NULL. With this patch applied, we also can get the same result.
Because the compiler will help us optimize the code.

So, we can remove unnecessary CONFIG_RT_GROUP_SCHED in rt_se_prio().
