fbdev: Wrap user-invoked calls to fb_blank() in helper

Handle fbcon during blanking in fb_blank_from_user(). First blank the
hardware, then blank fbcon. Same for unblanking. Update all callers and
resolve the duplicated logic.

With the new helper, fbdev's sysfb code no longer maintains fbcon state
by itself.
