[PATCH v2 1/2] sched: use existing helper functions to access ->avg_rt and ->avg_dl

[Shrikanth Hegde <sshegde@linux.vnet.ibm.com>]

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 used directly.

Instead use the helper function so that code becomes simpler and easy to
maintain later on. This patch doesn't intend any functional changes.
