[Intel-gfx] [PATCH] drv_module_reload: Unbind the right console driver

[Daniel Vetter]

We want to unbind fbcon, but only fbcon and only if it's there.

This was broken by the recent patch in 3.16-rc to kick out the vgacon
driver. I've forgotten to push out the relevant fix from the machine
used to create the kick vgacon patches.
