[SSSD] [PATCH] Two AD enumeration patches

Hi, attached are two more patches for issues I found when testing the POSIX detection code. [PATCH 1/2] AD: Only download domains that are set to enumerate This is a bug caused by the recent subdomain enumeration patches. The code always downloaded all domains even if subdomain_enumerate was set to false. This bug was not easy to spot, because the NSS frontend filtered the request for subdomain enumeration correctly, "just" the backend downloaded too much data. [PATCH 2/2] AD: Remove dead code As the subject says, just removing some dead code.
