perf sched: Fix memory leaks in 'perf sched latency'

Browse source

[ Upstream commit e68b1c0098 ]

The work_atoms should be freed after use.  Add free_work_atoms() to
make sure to release all.  It should use list_splice_init() when merging
atoms to prevent accessing invalid pointers.

Fixes: b1ffe8f3e0 ("perf sched: Finish latency => atom rename and misc cleanups")
