provider/azurerm: Event Hubs making the Location field idempotent

[tombuildsstuff]

Fixes a bug where the Location field caused a perpectual diff, with the Read function normalising the location and the Schema not - reported by @lstolyarov at the London HUG for Event Hub Authorization Rules (and Consumer Groups)

Tests pass:

$ envchain azurerm make testacc TEST=./builtin/providers/azurerm/ TESTARGS='-run=TestAccAzureRMEventHubConsumerGroup'
==> Checking that code complies with gofmt requirements...
go generate $(go list ./... | grep -v /terraform/vendor/)
