Ladi Prosek 50e1c4d90a virtio_ring: Make interrupt suppression spec compliant 
commit 0ea1e4a6d9b62cf29e210d2b4ba9fd43917522e3 upstream.

According to the spec, if the VIRTIO_RING_F_EVENT_IDX feature bit is
negotiated the driver MUST set flags to 0. Not dirtying the available
ring in virtqueue_disable_cb also has a minor positive performance
impact, improving L1 dcache load missed by ~0.5% in vring_bench.

Writes to the used event field (vring_used_event) are still unconditional.
