am7xxx: detect unexpected responses to AM7XXX_PACKET_TYPE_DEVINFO requests

Under some conditions, some devices like Philips/Sagemcom PPX projectors
return a strangely small packet (e.g. an AM7XXX_PACKET_TYPE_POWER with
header_data_len == 2) in reply to an AM7XXX_PACKET_TYPE_DEVINFO, hence
NOT providing useful device info.
