virtio: do not statically allocate root device
We shouldn't be statically allocating the root device object, so dynamically allocate it using root_device_register() instead. Also avoids this warning from 'rmmod virtio_pci': Device 'virtio-pci' does not have a release() function, it is broken and must be fixed Signed-off-by: Mark McLoughlin <markmc@redhat.com> Cc: Anthony Liguori <aliguori@us.ibm.com> Acked-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
