Viswas G 869ddbdcae scsi: pm80xx: corrected SATA abort handling sequence. 
Modified SATA abort handling with following steps:

1) Set device state as recovery.
2) Send phy reset.
3) Wait for reset completion.
4) After successful reset, abort all IO's to the device.
5) After aborting all IO's to device, set device state as operational.
