    zonectl: Consistently report ZAC conv. zones WP LBA
    
    On ZAC drives, conventional zones conventionally report a write pointer
    LBA of 0xffffffffffff. This field is 48 bits wide, unlike ZBC's 64 bits.
    
    Recognize both ZAC and ZBC all-ones behaviour in the WRITE POINTER LBA
    field to indicate non-valid information.
