[ Upstream commit 393da6cbb2ff89aadc47683a85269f913aa1c139 ] ftrace_graph_ret_addr() takes an `idx` integer pointer that is used to optimize the stack unwinding. Pass it a valid pointer to utilize the optimizations that might be available in the future. The commit is making riscv's usage of ftrace_graph_ret_addr() match x86_64.
