[SCSI] lpfc 8.3.18: Fix critical errors
Fix critical errors
- Update send_scsi_event to validate pnode pointer active before copying
the wwpn information.
- Add a message, mailbox_idle, and unlock before failing SECURITY_MGMT
or AUTH_PORT mailbox commands
- Prevent spin_lock_irqsave from being called twice in a row.
