drm/i915: Promote i915->mm.obj_lock to be irqsafe
The intent is to be able to update the mm.lists from inside an irqsoff
section (e.g. from a softirq rcu workqueue), ergo we need to make the
i915->mm.obj_lock irqsafe.
v2: can_discard_pages() ensures we are shrinkable
v3: Beware shadowing of 'flags'
Fixes: 3b4fa9640ccd ("drm/i915: Track the purgeable objects on a separate
eviction list")
