    Revert "ifconfig: abort if loading a module fails other than for ENOENT"
    
    This reverts commit 2c24ad3377a6f584e484656db8390e4eb7cfc119.
    
    This change causes some commands to fail, for example when working with
    renamed interfaces or when trying to list a nonexistent interface by
    name.
