Issue is fixed in VMware NSX-T Data Center 3.2.3.
If the conditions for this issue (hostswitch name change in maintenance mode or when redeploying edge) were already present in version less than 3.2.3 then issue can happen after even upgrade to 3.2.3. However after upgrading to 3.2.3 changing host switchname change in maintenance mode or when redeploying edge will not cause this issue.
Workaround:
Avoid replacing Edge node with a different switch name or change of switch name while Edge is in maintenance mode
