Log Message:
drm: Fix asynchronous attach logic for drm framebuffer devices.

The driver-specific sc_scheduled boolean flag was racy.  It is
necessary to use config_pending_incr/decr to hold up console
selection and userland start (and block detach, not that that works
yet) until the drmfb attach has completed.
