sd-bus: simplify bus_maybe_reply_error

sd_bus_reply_method_errno already does the same two checks
(sd_bus_error_is_set(error), r < 0) internally. But it did them in opposite
order. The effect is the same, because sd_bus_reply_method_errno falls back to
sd_bus_reply_method_error, but it seems inelegant. So let's simplify
bus_maybe_reply_error() to offload the job fully to sd_bus_reply_method_errno().

No functional change.
