[Bug]: test_route_withdraw_advertise fails consistently on T2 if upstream LC is multi-asic

[ysmanman]

Issue Description

The test case failed consistently if the upstream LC is multi-asic. Test expects the routes learnt on ASIC's are the same. But it turns out with 202405 image, ASIC's on upstream LC can learn route differently with recent optimization made for fast convergence.

Results you see

Test failed on T2 with multi-asic upstream LC.

Results you expected to see

Test should pass on T2 with multi-asic upstream LC.
