[PATCH] drm/nouveau/fbcon: fix oops without fbdev emulation

[Pavel Roskin]

Ben, David,

I would hate if Linux 4.14 is released without this fix, as it would
be a regression for my machine. As I mentioned, Linux 4.13 registers
nouveaufb even without the dock, but Linux 4.14 doesn't. And that
would cause an oops even if CONFIG_DRM_FBDEV_EMULATION is enabled.

Please let me know if any assistance is needed on my part to get the
patch merged.

Pavel
