Paul Stack 7ddc7211ca provider/azurerm: Guard against panic when importing arm_virtual_network (#9739)
Fixes #9410

When importing an azurerm_virtual_network that has no DNSServers,
terraform was throwing a panic as it was trying to dereference that list
of servers to set to state

This commit adds a simple check to make sure there are DNSServers before
dereferencing them
