    ahci - Improve SATA port link state sysctl output.
    
    This should now always print a meaningful state, instead of outputting
    "unknown" in any case where there is no device, no established
    communication with the device, or the phy is disabled.
    
    The case "no communication" is relevant, since this can probably occur
    in practice on notebooks where an optical drive may be disabled in the BIOS
    settings. Or it can probably occur when a disk drive is plugged into a SATA
    port, without connecting a power cable.
