Subject: [PATCH] drm/mm: Don't WARN if drm_mm_reserve_node

Jesse's BIOS fb reconstruction code actually relies on the -ENOSPC
return value to detect overlapping framebuffers (which the bios uses
always when lighting up more than one screen). All this fanciness
happens in intel_alloc_plane_obj in intel_display.c.

Since no one else uses this we can safely remove the WARN without
repercussions.
