  xlate: fix packets loopback caused by duplicate read of xcfgp.

Some functions, such as xlate_normal_mcast_send_mrouters, test xbundle
pointers equality to avoid sending packet back to in bundle. However,
xbundle pointers port from different xcfgp for same port are inequal.
This may lead to the packet loopback.

This commit stores xcfgp on ctx at first and always uses the same xcfgp
during one packet process period.
