Removed SDL_SYS_JoystickNeedsPolling().

It was simpler to just have the polling (actually: hotplug detection)
functions return immediately if it's not an appropriate time to poll.

Note that previously, if any joystick/controller was opened, we would poll
every time anyhow, skipping this function.
