[SCSI] ipr: qc_fill_rtf() method should not store alternate status register
The 'ctl' field of the 'struct ata_taskfile' is not really dual purpose, i.e. it is not intended for storing the alternate status register (which is mapped at the same address in the legacy IDE controllers) in the qc_fill_rtf() method. No other 'libata' driver except 'drivers/scsi/ipr.c' stores the alternate status register's value in the 'ctl' field of 'qc->result_tf', hence this driver should not do this as well...
