USB: pid_ns: ensure pid is not freed during kill_pid_info_as_uid
commit aec01c5895051849ed842dc5b8794017a7751f28 upstream.
Alan Stern points out that after spin_unlock(&ps->lock) there is no
guarantee that ps->pid won't be freed. Since kill_pid_info_as_uid() is
called after the spin_unlock(), the pid passed to it must be pinned.
