Subject: [PATCH] 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...
