rx: correctly count RX_PACKET_TYPE_VERSION packets

rx: correctly count RX_PACKET_TYPE_VERSION packets

Since the original IBM code import, rx statistics for counting incoming
packet types have inadvertently omitted RX_PACKET_TYPE_VERSION packets.
This results in rxdebug -rxstats always reporting 0 for the number of
version packets read.

A similar bug causes a debugging facility in rxi_ReceivePacket to emit
"*UNKNOWN*" instead of "version" for version packets.

Correct all versions of the offending logic.
