Subject: [PATCH] scsi: qla2xxx: Fix Inquiry command being dropped in Target
mode
References: bsc#1086327,FATE#324903
Git-commit: 8ea4faf829eb2ea36dd0c989965c029390d238f3
Patch-mainline: v4.18-rc1
When a connection is established, the target core session may not be
created immediately. Current code will drop/terminate the command based
on the session state. This patch will return BUSY status for any
commands arriving on wire before the session is created.
