[SCSI] qla4xxx: Remove hiwat code so scsi eh does not get escalated when we can make progress
Removed unnecessary hiwat code to free up the number available IOCBs. Eliminates unnecessary eh_ escalations due to inability to obtain IOCB pkt for marker. v2. - Remove define not used anymore and fix req_q_coun accounting.
