tracing: Remove orphaned function using_ftrace_ops_list_func().

Remove using_ftrace_ops_list_func() since it is no longer used. Using ftrace_ops_list_func() has been introduced by commit 7eea4fc ("tracing/stack_trace: Skip 4 instead of 3 when using ftrace_ops_list_func") as a helper function, but its caller has been removed by commit 72ac426 ("tracing: Clean up stack tracing and fix fentry updates"). So it is not called anymore.
