Puranjay Mohan 52fb34cf68 riscv: stacktrace: fix usage of ftrace_graph_ret_addr()
[ 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.
