proc_parse: fix while condition in parse_pid_status
In parse_pid_status there are 13 places where we do done++, so when
"done" is 13 it means that we have matched each of those 13 places and
we are ready to stop. In next lines we are not going to find anything.
So the right condition for the while loop is (done < 13).
