scsi: target: iscsit: Free cmds before session free
Description

In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsit: Free cmds before session free Commands from recovery entries are freed after session has been closed. That leads to use-after-free at command free or NPE with such call trace: Time2Retain timer expired for SID: 1, cleaning up iSCSI session.
