[PATCH 0/2] virtio-net/dim: fix irq moderation init failure unwind

net_dim_init_irq_moder() leaves dev->irq_moder dangling when profile
allocation fails.  virtio-net probe then skips virtqueue teardown if
that init fails after init_vqs().

Patch 1 makes the dim init failure path clear irq_moder, so
net_dim_free_irq_moder() is a no-op.

Patch 2 sends the virtio-net failure through the existing
free_irq_moder unwind (reset + del_vqs), matching the page-pool
failure path.

Patch 2 depends on patch 1.

Jianlin Shi (2):
  dim: clear irq_moder on init failure
  virtio-net: unwind VQs when irq moderation init fails
