Subject: [PATCH] Remove disable dropdown behavior

Now that we bind the ULS dialog to the checkbox element,
(see c08ae11) the default behaviour of the checkbos is prevented,
so it is impossible for the dropdown to ever
be shown when ULS is enabled and clicked so this code no longer
serves any purpose.

Depends-On: I97a69c30b27cb1ded06451389e086229561c3589
Change-Id: Ic9d03dea12ee8bb2d7430eccd70e4343e3805d36
