Subject: [PATCH] lib.modules: compute disabled module list early

isDisabled gets the list of disabledModules ready when it's only given
two attributes, so when it's passed the third argument, it just has to
call `elem` on its precomputed list. This was being used in the graph
right below, but now in module filtering.
