[SCSI] libsas: don't treat underrun as an error on SMP tasks
All SMP tasks sent through bsg generate messages like:
sas: smp_execute_task: task to dev 500605b000001450 response: 0x0 status 0x81
Three times (because the task gets retried). Firstly, don't retry
either overrun or underrun (the data buffer isn't going to change size)
and secondly, just report the underrun but don't set an error for it.
This is necessary so bsg can report back the residual.
