    iflib: Set the get counter routine prior to attaching the interface
    
    This ensures other threads, e.g. ioctl threads, see the correct counter
    routine once after the interface has been attached.
    
    This change partially reverts commit 23ac9029f96b, which for unclear
    reason moved setting the get counter routine after ether_ifattach().
