[SCSI] lpfc 8.3.24: Extend BSG infrastructure and add link diagnostics
Extend BSG infrastructure and add link diagnostics:
- Removed unnecessary copies in handling pass-through mbox cmds.
- Add embedded SLI_CONFIG support for BSG.
- Add multibuffer support.
- Implemented the setting up and tearing down Lancer FC device for performing
internal and external loopback diagnostic tests.
- Implemented the driver support for performing new link diagnostic tests
