SF: Do not deref empty std::optional<PowerMode>
In I3a2eae4efc4a5c6113700a9ca9e9b261e364a878, a display's power mode is
std::nullopt (unknown) until the first setPowerMode. The condition to
power on the display from that state relies on undefined behavior, as
it dereferences std::nullopt. It only works because PowerMode::OFF is
0 and the memory happens to be zeroed.
