    graid: MFC: unbreak Promise RAID1 with 4+ providers
    
    Fix a problem in graid implementation of Promise RAID1 created with 4+ disks.
    Such an array generally works fine until reboot only due to a bug
    in metadata writing code. Before the fix, next taste erronously created
    RAID1E (kind of RAID10) instead of RAID1, hence graid used wrong offsets
    for I/O operations.
    
    The bug did not affect Promise RAID1 arrays with 2 or 3 disks only.
