[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
