sched/fair: Use existing helper functions to access ->avg_rt and ->avg_dl
This is a minor code simplification. There are helper functions called
cpu_util_dl() and cpu_util_rt() which gives the average utilization of DL
and RT respectively. But there are few places in code where these
variables are open-coded.
Instead use the helper function so that code becomes simpler and easier to
maintain later on.
No change in functionality intended.
