This series fix two vqs leak:
1. Do delete vqs on the error path in virtio_blk_device_realize().
2. Do delete vqs in virtio_iommu_device_unrealize() to fix another leaks.

v2->v1:
- Fix incorrect free in virtio_blk_device_realize, it will cause a uaf.

v3->v2:
- Also clean 's->as_by_busptr' hash table in virtio_iommu_device_unrealize.(Suggested by Stefano Garzarella)

v4->v3:
- update patch2/2 subject message and move g_hash_table_destroy() at the beggining of unrealize().

Pan Nengyuan (2):
  virtio-blk: delete vqs on the error path in realize()
  virtio-iommu: avoid memleak in the unrealize
