[PATCH 12/12] pid: Remove the now unused kill_pg kill_pg_info and __kill_pg_info

["Eric W. Biederman" <ebiederm@xmission.com>]

Now that I have changed all of the in-tree users remove the old
version of these  functions.  This should make it clear to any
out of tree users that they should be using kill_pgrp kill_pgrp_info
or __kill_pgrp_info instead.
