    passthrough: pt_bar_mapping etc.: use correct CMD for PCI BAR mapping etc.
    
    dbb8aafa702b8b4f5568e08641d98471fd04e0f8 has a bug:
    The virtual CMD value we get from reg_entry->data is not the proper
    value because reg_entry->data only holds the emulated bits and the
    PCI_COMMAND_IO/PCI_COMMAND_MEMORY bits are not in it.  Instead, we can
    use pt_pci_read_config(&ptdev->dev, PCI_COMMAND, 2) to get the proper
    value.
    
    We should only update the mapping of the related BAR, NOT the mappings
    of ALL BARs.
    
    In pt_exp_rom_bar_reg_write(), we should also update the mapping. And
    for PCI_ROM_SLOT, when the PCI_ROM_ADDRESS_ENABLE bit is 0, we should
    not have the mapping.
