[SCSI] isci: performance-fix, shorten default "no outbound task" timeout
"No task timeout timer reduced from 20 to 2 This timer controls how long the SCU hardware will hold open the TX side of the connection before sending a DONE. The timer allows the hardware to attempt to optimize the DONE/CLOSE behavior to allow for new COMMAND IU to be posted. In practice closing the connection quicker is better."
