tools: ynl-gen: always construct struct ynl_req_state

struct ynl_req_state carries reply-related info from generated code
into generic YNL code. While we don't need reply info to execute
a request without a reply, we still need to pass in the struct, because
it's also where we get the pointer to struct ynl_sock from. Passing NULL
results in crashes if kernel returns an error or an unexpected reply.

Fixes: dc0956c98f11 ("tools: ynl-gen: move the response reading logic into YNL")
