PATCH 1/6 lpfc 8.3.17: Code Cleanup and Locking fixes

- Move Unload flag earlier in vport deletei to stop ELS traffic
- Replaced some unnecessary spin_lock_irqsave with spin_lock_irq
- Fixed circular spinlock dependency between low-level driver and SCSI midlayer
- Remove duplicate code from lpfc_els_retry routine
- Make all error values negative
