perf ui browser: Fix segfault caused by off by one handling END key
$ perf record ls $ perf report Press 'down enter end' Result: Program received signal SIGSEGV, Segmentation fault. The UI browser, used on a argv array would access past the end of the array on SEEK_END because it wasn't using 'nr_entries - 1', fix it.
