FIXUP: sched/tune: add fixes missing from a previous patch
The previous patch:
e7ce26f - FIXUP: sched/tune: fix accounting for runnable tasks
squashed together patches of a series to fix SchedTune's accounting
issues. However, in the consolidation and cleanup of the series to merge
in the Android Common Kernel, we somehow missed a couple of important
changes:
1) the schedtune_exit function is not more required, because e7ce26f
fixes accounting of exiting tasks in a different way
2) the schedtune_initialized flag was not set at the end of
scheddtune_init_cgroup() thus failing to enabled SchedTune at boot.
This patch thus is to be considered an integration of e7ce26f.

[jstultz: Cherry-picked from android-3.18. It should be noted that
some of this patch was already applied in the 4.4 patches (schedtune_exit
doesn't exist for example), but this patch just ensures things are totally
synced up]
