function_graph: Make ftrace_push_return_trace() static
commit d125f3f866df88da5a85df00291f88f0baa89f7c upstream.
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.
