    fastloader-GEOS: Add missing track masking to 1581 reads
    
    Fix a missing bit mask in the 1581-read path of load_geos() because
    GEOS already sends the READ command with bit 7 set if it only needs
    the link pointer of a sector, even though the bit is only checked in
    the TRANSMIT command.
