drm/i915: Remove struct_mutex for destroying framebuffers
We do not need to hold struct_mutex for destroying drm_i915_gem_objects
any longer, and with a little care taken over tracking
obj->framebuffer_references, we can relinquish BKL locking around the
destroy of intel_framebuffer.
v2: Use atomic check for WARN_ON framebuffer miscounting
