For mirroring, ECMP index should not come from parent flow

In the case of mirror to an ECMP destination, we can not take the
ECMP index that is set in the flow of the parent (the flow/packet
that is mirrored). Hence, set the ECMP index to -1.

Also, there isn't a flow that maps to the mirror packet. So,
extract all the information that is needed from the parent flow and
set the flow index in the forrwarding metadata to -1.
