riscv: stacktrace: Fixup ftrace_graph_ret_addr retp argument
[ Upstream commit 5c3022e4a616d800cf5f4c3a981d7992179e44a1 ]
The 'retp' is a pointer to the return address on the stack, so we
must pass the current return address pointer as the 'retp'
argument to ftrace_push_return_trace(). Not parent function's
return address on the stack.
Fixes: b785ec129bd9 ("riscv/ftrace: Add HAVE_FUNCTION_GRAPH_RET_ADDR_PTR support")
