scsi: lpfc: SLI path split: Refactor Abort paths

This patch refactors the Abort paths to use SLI-4 as the primary interface.

 - Introduce generic lpfc_sli_prep_abort_xri jump table routine

 - Consolidate lpfc_sli4_issue_abort_iotag and lpfc_sli_issue_abort_iotag
   into a single generic lpfc_sli_issue_abort_iotag routine

 - Consolidate lpfc_sli4_abort_fcp_cmpl and lpfc_sli_abort_fcp_cmpl into a
   single generic lpfc_sli_abort_fcp_cmpl routine

 - Remove unused routine lpfc_get_iocb_from_iocbq

 - 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.
