drmmode_set_scanout_pixmap_gpu(pix) adds drmmod->fb_id through a call to drmmode_xf86crtc_resize(), but on a subsequent drmmode_set_scanout_pixmap_gpu(NULL) it would not remove the fb. This keeps the crtc marked as busy, which causes the dgpu to not being able to runtime suspend, after an output attached to the dgpu has been used once. Which causes burning through an additional 10W of power and the laptop to run quite hot. This commit adds the missing remove fb call, allowing the dgpu to runtime suspend after an external monitor has been plugged into the laptop. Note this also makes drmmode_set_scanout_pixmap_gpu(NULL) match the behavior of drmmode_set_scanout_pixmap_cpu(NULL) which was already removing the fb.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
