function_graph: ftrace_graph_ret_addr(); there can be only one!

I noticed a slight bug in ftrace_graph_ret_addr() for when HAVE_FUNCTION_GRAPH_RET_ADDR_PTR was defined and fixed it up. I then noticed it was buggy when not defined. Looking for an architecture that did not have it defined, I couldn't find any. So I removed it.
