drm/i915: Only bump refcnt on objects scheduled for eviction

Browse source

Incrementing the reference count on all objects walked when searching
for space in the aperture is a non-neglible amount of overhead. In fact,
we only need to hold on to a reference for objects that we will evict,
so we can therefore delay the referencing until we find a suitable hole
and only add those objects that fall inside.
