Ben Skeggs 028791bb7d drm/nouveau/kms: restore fbcon after display has been resumed
Under some complicated circumstances (boot, suspend, resume, attach
second display, suspend, resume, suspend, detach second display,
resume, suspend, attach second display, resume), the fb_set_suspend()
call can somehow result in a modeset being attempted before we're
ready for it and things blow up in fun ways.

Running display init first fixes the issue.
