ftrace: Remove unused unregister_ftrace_function_probe_all() function

Browse Source 
There are no users of unregister_ftrace_function_probe_all(). The only probe
function that is used is unregister_ftrace_function_probe_func(). Rename the
internal static function __unregister_ftrace_function_probe() to
unregister_ftrace_function_probe_func() and make it global.

Also remove the PROBE_TEST_FUNC as it would be always set.
