OPTE now prevents itself from being unloaded if its underlay state is set. Currently, underlay setup is performed only once, and it seems to be the case that XDE can be unloaded in some scenarios (e.g., `a4x2` setup). However, a consequence is that removing the driver requires an extra operation to explicitly clear the underlay state. This PR adds this operation to the `cargo xtask virtual-hardware destroy` command. This is currently blocked on opte#485 being approved/merged. Closes #5314.
