[Bug]: Arista 7050cx3 failed to setup vnet route with vxlan_ecmp_utils APIs

[xwjiang-ms]

Issue Description

In 7050cx3 T1, when trying to setup vnet route with APIs in tests/common/vxlan_ecmp_utils.py, it would fail with SAI error, but mlnx and cisco platform looks fine, seems there are some gaps between sonic-mgmt APIs and SAI APIs
