bitbake: runqueue: Fix multiconfig deferred task sstate validity caching issue

We were testing the validity of deferred tasks setscene status "up front" which
is very unlikely to succeed and leads to cache invalidation issues. With the
change to rebuild the deferred task list, this status becomes out of sync. The
result was tasks being executed when they should not have been leading to extra
work for the build unnecessarily.

Instead, don't process validity status for deferred tasks and assume their
data will become available. If it doesn't, this will now result in a build
error as the setscene task will fail and the main task will run instead.

In theory we could try and track the state changes in the deferred list and
re-test validity then but I'm not sure it is worth the effort when the other
code path and errors in setscene tasks will give a pretty good idea of what
is happening anyway.
