[Calico/VPP NSM integration] Memif2Memif case doesn't work with Calico VPP

[Bolodya1997]

Issue

Memif2Memif with direct memif enabled test fails on both kind and packet clusters with Calico VPP:

1. In NSM logs there are no errors.
2. All sockets are configured in VPP.
3. VPP ping doesn't work in both sides.

Calico currently doesn't provide any guarantees for the working memif, so the root cause for the issue can both be on the NSM or on the Calico side.

Probable solution

Disable direct memif for Calico VPP integration. Disabling direct memif doesn't work, so we need another solution.

Memif2Memif is working with Calico VPP (included in basic suite):
