Subject: scsi: qla2xxx: Avoid flush_scheduled_work() usage
Patch-mainline: v6.1-rc1
Git-commit: 3cb0643a9aae7cf360102a6a9db47f5ce9fefdb1
References: bsc#1203935

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.
