scsi: lpfc: Revise NVME module parameter descriptions for better clarity

The descriptions for lpfc_xri_split and lpfc_enable_fc4_type were
poor. Revise for better understanding:

  lpfc_xri_split - Percentage of FCP XRI resources versus NVME
  lpfc_enable_fc4_type - Enable FC4 Protocol support - FCP / NVME
