Steven Rostedt (VMware) d125f3f866 function_graph: Make ftrace_push_return_trace() static ...

As all architectures now call function_graph_enter() to do the entry work,
no architecture should ever call ftrace_push_return_trace(). Make it static.

This is needed to prepare for a fix of a design bug on how the curr_ret_stack
is used.
