iommu/amd: Don't take domain->lock recursivly The domain_flush_devices() function takes the domain->lock. But this function is only called from update_domain() which itself is already called unter the domain->lock. This causes a deadlock situation when the dma-address-space of a domain grows larger than 1GB. Cc: stable@kernel.org Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
