top: fix a segfault when -p switch specified invalid pid

Browse Source 
In attempting to keep at least one task visible when
scrolling vertically, a negative task index would be
produced when pid monitoring was in effect and no
matching pid was found.

Since there were already other conditions where no
task might displayed, the faulty source line has been
removed.
