ata fixes for 6.10-rc4

- Fix a bug where the SCSI Removable Media Bit (RMB) was incorrectly set
    for hot-plug capable (and eSATA) ports. The RMB bit means that the
    media is removable (e.g. floppy or CD-ROM), not that the device server
    is removable. If the RMB bit is set, SCSI will set the removable media
    sysfs attribute.
    If the removable media sysfs attribute is set on a device, GNOME/udisks
    will automatically mount the device on boot.
    We only want to set the SCSI RMB bit (and thus the removable media
    sysfs attribute) for devices where the ATA removable media device bit
    is set.
