drm/vblank: Use memory barriers optimized for atomic_t instead of generics.
Documentation/atomic_ops.txt tells us that there are memory
barriers optimized for atomic_inc and other atomic_t ops.
Use these instead of smp_wmb(), and also to make the required
memory barriers around vblank counter increments more explicit.
