Subject: [PATCH 2/3] tracing: Remove orphaned function using_ftrace_ops_list_func().

Remove using_ftrace_ops_list_func() since it is no more
used.

using_ftrace_ops_list_func() has been introduced by commit
7eea4fce0246 ("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 72ac426a5bb0
("tracing: Clean up stack tracing and fix fentry updates").
So it is not called anymore.
