Chris Wilson e32da7adaf drm/i915: Protect gen7 irq_seqno_barrier with uncore lock ...

Faced with sporadic machine hangs on gen7, that mimic the issue of
concurrent writes to the same cacheline and seem to start with
commit 9b9ed30936 (drm/i915: Remove forcewake dance from seqno/irq
barrier on legacy gen6+), let us restore the spinlock around the mmio
read.
