scsi: lpfc: Expand setting ELS_ID field in ELS_REQUEST64_WQE

ELS_ID field for ELS_REQUEST64_WQE is not filled out when FIP is not
supported by the HBA.

Move setting ELS_ID logic into __lpfc_sli_prep_els_req_rsp_s4(), and remove
ELS_ID FIP dependency logic from lpfc_sli_prep_wqe().

Introduce PLOGI ELS_ID and as a result update wqe_els_id_MASK because PLOGI
ELS_ID = 0x4 occupies up to 3 bits.

While in __lpfc_sli_prep_els_req_rsp_s4() routine, remove SLI3-isms.
