[EVPN VXLAN] Orchagent crash when removing a Vlan that is mapped to VNI

[dellwuchuan]

Description

The issue is that when remove a VLAN which is mapped to VNI, FRR docker would crash.
The CLI shouldn't allow it.

Steps to reproduce the issue:

Steps:

config vlan add 1000

config vlan member add 1000 Ethernet60

config vxlan map add vtep101032 1000 7385123

config vlan member del 1000 Ethernet60

config vlan del 1000 -----> This should throw error since there is vxlan map but it doesn't leading to orchagent crash

Describe the results you received:

FRR docker would crash:
Error response from daemon: Container bdc5e2d094f015ef1a8a390983df23c9ec15292cc4c2aef5760e40e869f94b1d is not running

Describe the results you expected:

FRR docker should not crash
