[SCSI] lpfc 8.3.14: PCI fixes and enhancements

- Allow enabling MSI-X intterupts with fewer vectors than requested
  by looking at the return value from pci_enable_msix.
- Implemented driver PCI AER error handling routines for supporting
  AER error recovering on SLI4 devices.
- Remove redundant SLI_ACTIVE checks
