[SCSI] lpfc 8.3.0 : Fix several minor issues

- Avoid polling HBA Error Attention when HBA's PCI channel is offline
  due to PCI EEH

- Fix handling of RSCN with non-zero event qualifiers

- Remove unnecessary sleeps during HBA initialization which slow down
  driver load

- Fix internal and external loopback on FCoE HBAs

- Fix incorrect decrement of cmd_pending count in lpfc_queuecomand
  error path

- Fix reporting of port busy events to management application

- Rename lpfc_adjust_queue_depth() to lpfc_rampdown_queue_depth() for
  consistency with its partner lpfc_rampup_queue_depth()

- Delete redundant lpfc_cmd->start_time = jiffies assignment in
  lpfc_queuecommand()

- Fix handling for ELS, mailbox and heartbeat time outs in the worker
  thread by removing unnecessary checking of the work_port_events
  flags.

- Fix NULL pointer dereference in lpfc_prep_els_iocb

- In lpfc_device_recov_npr_node(), move clearing of NLP_NPR_2B_DISC
  flag after call to lpfc_cancel_retry_delay_tmo() to keep
  targets-in-discovery count correct

- Remove lpfc_probe_one()'s call to scsi_scan_host() which could cause
  concurrent SCSI scans to step on each other
