perf_events: Move code around to prepare for cgroup

In particular this patch move perf_event_exit_task() before
cgroup_exit() to allow for cgroup support. The cgroup_exit()
function detaches the cgroups attached to a task.

Other movements include hoisting some definitions and inlines
at the top of perf_event.c
