[SCSI] lpfc 8.1.5 : Fix cleanup code in the lpfc_pci_probe_one() error code path

Browse Source 
Fix cleanup code in the lpfc_pci_probe_one() error code path.

This changes the original patch by:
  - hardsetting the return value from lpfc_pci_probe_one() to
    -ENODEV (negative value) if we fail attach
  - removes the checks from lpfc_pci_remove_one() validating the
    host and phba pointers as it's no longer needed.
