Gautam Dawar 5a52215009 vhost-vdpa: free iommu domain after last use during cleanup ... Currently vhost_vdpa_cleanup() unmaps the DMA mappings by calling `iommu_unmap(v->domain, map->start, map->size);` from vhost_vdpa_general_unmap() when the parent vDPA driver doesn't provide DMA config operations. However, the IOMMU domain referred to by `v->domain` is freed in vhost_vdpa_free_domain() before vhost_vdpa_cleanup() in vhost_vdpa_release() which results in NULL pointer de-reference. Accordingly, moving the call to vhost_vdpa_free_domain() in vhost_vdpa_cleanup() would makes sense. This will also help detaching the dma device in error handling of vhost_vdpa_alloc_domain(). This issue was observed on terminating QEMU with SIGQUIT.
