[SCSI] libsas: Delay issuing ABORT TASK TMF until the error handler
sas_task_abort() should simply abort the upper-level SCSI command and wait until the error handler to send the actual ABORT TASK command. By deferring things to the EH we simplify the concurrency coordination and eliminate some race conditions. Note that sas_task_abort has a few hooks to handle libsas internal commands properly too. Also rename do_sas_task_abort to __sas_task_abort just in case we really want to abort the task *right now* and we don't have a scsi_cmnd attached to the command. This is a hook for libata internal commands to abort. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
