Don't send k_ePS4FeatureReportIdSerialNumber to Bluetooth PS4 controllers

This isn't supported over Bluetooth and might be causing issues with fake PS4 controllers.

Note that this change should NOT be ported to SDL2, as device->is_bluetooth is not set from hidapi there and is only detected by seeing which reports are valid.
