Puranjay Mohan 393da6cbb2 riscv: stacktrace: fix usage of ftrace_graph_ret_addr() ...

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.
