Steve Sistare ef3a3f6a29 vfio/type1: exclude mdevs from VFIO_UPDATE_VADDR ... Disable the VFIO_UPDATE_VADDR capability if mediated devices are present. Their kernel threads could be blocked indefinitely by a misbehaving userland while trying to pin/unpin pages while vaddrs are being updated. Do not allow groups to be added to the container while vaddr's are invalid, so we never need to block user threads from pinning, and can delete the vaddr-waiting code in a subsequent patch.
