virtio: fix boot device hunting in qemu with virtio

Commit 70101c3217ae ("virtio: mmio: Return error codes on probe
failures") returns -ENODEV where it would return 0 before. That path is
apparently hit in qemu and breaks boot device discovery
(virtio_bootdev_hunt() expects only ENOENT). So return -ENOENT in
that path instead.
The remaining two error returns in the function are untouched as I
don't know where they play a role.
