Correct VLAN_RANGE_REGEX.

It appears that the VLAN_RANGE_REGEX being used currently doesn't
correctly match vlan's above 999 resulting it applying interfaces even
when the vlan interface already exist.

Correct the vlan range regex so that it correctly matches - based on the
regex used elsewhere in the module.
