arm64: stacktrace: fix the usage of ftrace_graph_ret_addr()
ftrace_graph_ret_addr() takes an 'idx' integer pointer that is used to
optimize the stack unwinding process. arm64 currently passes `NULL` for
this parameter which stops it from utilizing these optimizations.
Further, the current code for ftrace_graph_ret_addr() will just return
the passed in return address if it is NULL which will break this usage.
Pass a valid integer pointer to ftrace_graph_ret_addr() similar to
x86_64's stack unwinder.
