Menuselect: Fix incorrect enabling on failed deps

This corrects a situation where menuselect can incorrectly enable a
module by default that has defaultenabled set to "no" and has
failed/non-selected dependencies. The bug is due to an inverted test
when checking for whether the given module should be set to enabled by
default on load.
