res_rtp_asterisk:  Fix packet stats on bridged connection

rxcount, txcount, rxoctetcount and txoctetcount weren't being calculated
for bridged streams because the calulations were being done after the
bridged short-circuit.  Actually, rxoctetcount wasn't ever being calculated.

Moved the calculations so they occur for all valid received packets and
all transmitted packets.  Also added rxoctetcount and txoctetcount to
ast_rtp_instance_stat.
