perf top: Fix uninitialized 'counter' variable
builtin-top.c has an uninitialized variable.
gcc(version 4.5.1) warns about it and it results in build failure:
builtin-top.c: In function 'display_thread':
builtin-top.c:518:9: error: 'counter' may be used uninitialized
This situation can indeed trigger, if the getline() call in
prompt_integer() fails.
