Subject: scsi: qla2xxx: flush IO on chip reset or sess delete
Patch-mainline: v5.1-rc1
Git-commit: 51fd6e6351a62da87a7eb7b059d34056d73e68e5
References: bsc#1123034 bsc#1124541 bsc#1131304 bsc#1127988

On Transmit respond in target mode, if the chip is already reset or the
session is already deleted, then advance the command to the free step.
There is no need to abort the command, because the chip has already flushed
it.
