lib: remove prio_heap

The prio_heap code is unused since commit 889ed9c ("cgroup: remove css_scan_tasks()"). It should be compiled out to shrink the binary kernel size which can be done via introducing CONFIG_PRIO_HEAD or by removing the code. We can simply recover the code from git when needed, so it would be better to remove it IMO. Signed-off-by: Lai Jiangshan <[email protected]> Acked-by: Tejun Heo <[email protected]> Cc: "David S.
