terraform plugin fails to describe instance by tag

[kaufers]

The terraform instance plugin's DescribeInstances may fail if there are multiple groups. During the tag checking, if a tag does not match then the following is executed:

							continue scan

This is tied to an outer for loop:

	// now we scan for <instance_type.instance-<timestamp> as keys
scan:
	for t, vm := range localSpecs {

		for k, v := range vm {
			matches := re.FindStringSubmatch(string(k))

The other loops is a 2D array with the resource type as the 0th element. This element will be the resource type; if this outer for loop is continued then all of the elements of the same resource type are not processed.

The fix is to move the scan: declaration to the next for loop so all of the resources are processed.
