…)" (#2773) This reverts commit 750e064. Reverts the PR #2756 The fix added breaks the previously added workaround #2626. Hence requesting to revert the fix. Once we find a proper solution for sonic-net/sonic-buildimage#12361 we need to reintegrate this PR

Fixes sonic-net/sonic-buildimage#14949
What I did
Sometime during config reload, EVPN NVO table arrives later than remote VNI table entries. In such scenarios, remote vni entries are ignored and this leads to traffic loss. Added fix to retry instead of ignoring.
Why I did it
To fix race condition as stated in the description
How I verified it
Added UT to verify.
