drm/gem: Always initialize the gem object in object_init
At least drm/i915 expects that the obj->dev pointer is set even in

call i915_gem_object_free which needs to deref obj->base.dev to get at
the slab pointer in the device private structure. And the shmem
allocation can easily fail when userspace is hitting open file limits.

Merge branch 'drm-next-3.14' of git://people.freedesktop.org/~agd5f/linux into drm-next
New tree with the INFO ioctl merge fixed up. This also adds a couple
of additional minor fixes.
A few more changes for 3.14, mostly just bug fixes. Note that:
drm/radeon: add query to fetch the max engine clock.
will conflict with 3.13 final, but the fix is pretty obvious.
