    bhyve: Treat the COMMAND register for PCI passthru devices as emulated

    Don't pass through writes of the command register through to the
    physical device.  These registers do not need to be in sync, and in
    some cases (e.g. when the guest is sizing the BAR and temporarily
    disables decoding), the states need to diverge.
