Baoquan He ec62b1ab0f iommu/amd: Check if domain is NULL in get_domain() and return -EBUSY 
In get_domain(), 'domain' could be NULL before it's passed to dma_ops_domain()
to dereference. And the current code calling get_domain() can't deal with the
returned 'domain' well if its value is NULL.

So before dma_ops_domain() calling, check if 'domain' is NULL, If yes just return
ERR_PTR(-EBUSY) directly.
