osmo-bts-trx: Relax validation to allow TRX data bursts without paddingpespin/sysmocell5000
Original OpenBTS transcievers add 2 bytes of padding to the end of data bursts, having in total 158 bytes. As those two extra bytes are being ignored after the initial validation, let's relax this validation a bit in order to accept transcievers that decide no to send these two extra bytes.
