scsi: qla2xxx: Avoid flush_scheduled_work() usage 

Although qla2xxx driver is calling schedule_{,delayed}_work() from 10
locations, I assume that flush_scheduled_work() from qlt_stop_phase1()
needs to flush only works scheduled by qlt_sched_sess_work(), for this loop
continues while "struct qla_tgt"->sess_works_list is not empty.
