Chris Wilson edf6b76f64 drm/i915: Add smp_rmb() to busy ioctl's RCU dance 
In the debate as to whether the second read of active->request is
ordered after the dependent reads of the first read of active->request,
just give in and throw a smp_rmb() in there so that ordering of loads is
assured.

v2: Explain the manual smp_rmb()
