scsi: qla2xxx: Fix hang due to session stuck
stable inclusion from stable-v5.10.110 commit f296e888e921bb2c3615da4142024609ed6adbfa bugzilla: https://gitee.com/openeuler/kernel/issues/I574AL Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=f296e888e921bb2c3615da4142024609ed6adbfa -------------------------------- commit c02aada0 upstream. User experienced device lost. The log shows Get port data base command was queued up, failed, and requeued again. Every time it is requeued, it set the FCF_ASYNC_ACTIVE. This prevents any recovery code from occurring because driver thinks a recovery is in progress for this session. In essence, this session is hung. The reason it gets into this place is the session deletion got in front of this call due to link perturbation. Break the requeue cycle and exit. The session deletion code will trigger a session relogin.
