Chris Wilson 349ab9192c drm/i915/guc: Make wq_lock irq-safe 
Following the use of dma_fence_signal() from within our interrupt
handler, we need to make guc->wq_lock also irq-safe. This was done
previously as part of the guc scheduler patch (which also started
mixing our fences with the interrupt handler), but is now required to
fix the current guc submission backend.

v4: Document that __i915_guc_submit is always under an irq disabled
section
v5: Move wq_rsvd adjustment to its own function

Fixes: 67b807a892 ("drm/i915: Delay disabling the user interrupt for breadcrumbs")
