scsi: qla2xxx: Fix hang due to session stuck

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.
