realtek: fix RTL838x receive tag decoding
Commit dc9cc0d3e2a1 ("realtek: add QoS and rate control") replaced a
16 bit reserved field in the RTL83xx packet header with the initial
cpu_tag word, shifting the real cpu_tag fields by one. Adjusting for
this new shift was partially forgotten in the new RX tag decoders.
This caused the switch to block IGMP, effectively blocking IPv4
multicast.
The bug was partially fixed by commit 9d847244d9fd ("realtek: fix
RTL839X receive tag decoding")
Fix on RTL838x too, including correct NIC_RX_REASON_SPECIAL_TRAP value.
