[media] rc/imon: fix ffdc device detection oops
There's a nasty bug that slipped in when the rc device interface was altered, only affecting the older 0xffdc imon devices. We were trying to access ictx->rdev->allowed_protos before ictx->rdev had been set. There's also an issue with call ordering that meant the correct keymap wasn't getting loaded for MCE IR type 0xffdc devices.
