[SCSI] lpfc 8.3.0 : Fix multiple NPIV issues

[SCSI] lpfc 8.3.0 : Fix multiple NPIV issues

- Fix lock up on rmmod with vports defined by having
  lpfc_pci_remove_one() invoke fc_vport_terminate() to remove all the
  vports before invoking fc_remove_host() for the physical port

- Fix echotest failure when NPIV is enabled

- Add the vport_disable function to the physical port's transport
  template to make the vport disable attribute visible

- Set the vport state to DISABLE on create if the disable flag is
  true

- Call lpfc_alloc_sysfs_attr() for vports so that statistical data
  collection works on them

- Support setting a vport's symbolic name via sysfs by writing to
  /sys/class/fc_vport/vportX/symbolic_name

- Fix create vport fails when link is down or in loop mode.  Should be
  able to be create vports any time NPIV is enabled

- Fix slow vport deletes when deleting multiple vports at once
