Backport

This PR is auto-generated from #31091 to be assessed for backporting due to the inclusion of the label 1.2-backport.

This fixes a bug introduced in #30639 in which initialising a module will fail if that module contains both a provider block and a module call using for_each.

This bug was introduced in https://github.com/hashicorp/terraform/pull/30639/files#diff-95e614048e1ba4ba7621e22ba67cfe5c8acd386e5540b8c92c267d2fd1b3d31eR31-R55 by removing a variable scoped to a for loop (var nope) and instead overwriting noProviderConfigRange. This meant that the error at https://github.com/hashicorp/terraform/pull/30639/files#diff-95e614048e1ba4ba7621e22ba67cfe5c8acd386e5540b8c92c267d2fd1b3d31eR181 would be triggered if the parent module contained a provider block, not the child.

Fixes #31081

Test case

There are no tests in code for this behaviour. Highly recommend adding them as follow up. I manually tested this using the example below, kindly provided by @knbnnate.
