Wang Nan c4f035473d perf tools: Set vmlinux_path__nr_entries to 0 in vmlinux_path__exit 
Original vmlinux_path__exit() doesn't revert vmlinux_path__nr_entries to
its original state. After the while loop vmlinux_path__nr_entries
becomes -1 instead of 0.

This makes a problem that, if runs twice, during the second run
vmlinux_path__init() will set vmlinux_path[-1] to strdup("vmlinux"),
corrupts random memory.

This patch reset vmlinux_path__nr_entries to 0 after the while loop.
