Use innerpacket's destip as source ip while doing Tx Port mirroring

When Transmit port mirroring is enabled, packet received on Fabric
interface is right now mirrored using the source IP of the inner packet.
This results in RPF failure on Analyzer VM's compute node because the
compute node which is doing the port mirroring is using other compute
node's VM IP.

As a fix, if mirroring is Tax mirroring, rather using inner packets
source ip, dest ip is used, so that Analyzer VM's RPF will not have any
issues
