scsi: lpfc: SLI path split: Refactor misc ELS paths 

This patch refactors the remaining ELS paths to use SLI-4 as the primary
interface. Paths include RRQ, RSCN, unsolicited ELS RQST and RSP paths, ELS
timeouts, etc.:

 - Remove unused routines lpfc_sli4_bpl2sgl and lpfc_sli4_iocb2wqe

 - Conversion away from using SLI-3 iocb structures to set/access fields in
   common routines. Use the new generic get/set routines that were added.
   This move changes code from indirect structure references to using local
   variables with the generic routines.

 - Refactor routines when setting non-generic fields, to have both SLI3 and
   SLI4 specific sections. This replaces the set-as-SLI3 then translate to
   SLI4 behavior of the past.
