[SCSI] lpfc 8.3.21: RRQ Implementation fixes
RRQ Implementation fixes - Added checks to prevent a call to findnode_did in clr_active_rrq - Added the del_sync_timer call for the rrq_tmr to the stop_hba_timers routine. - Added a check in __lpfc_set_active_rrq for the driver unloading to prevent adding an rrq when the driver is being removed. - Add code to scsi_iocb_cmpl to check for the remote stop and add the rrq. - Added the same check to els retry. - Added code to compare the source did in the els rrq to the vports did and chose the right exchange ID. - Initialize the start_cmd pointer to indicate when we have looped through all of the scsi buffers. - Remove the need for the lock around the clearing of the active bit in the rrq. - Added code to clean the els and fcp xri aborted list and remove the all of the RRQs for a deleted vport.
