    usb-storage: always set the allow_restart flag
    
    This patch (as1000) sets the SCSI allow_restart flag for USB disk
    devices.  In theory this should never hurt, and there definitely are
    devices out there (such as the Seagate 250-GB external drive) which
    need the flag to be set.
