Revert "scsi: lpfc: SLI path split: Refactor fast and slow paths to native SLI4"

This reverts commit c56cc7fe.

LTS 5.15 pulled in several lpfc "SLI Path split" patches.  The Path
Split mods were a 14-patch set, which refactors the driver from
to split the sli-3 hw (now eol) from the sli-4 hw and use sli4
structures natively. The patches are highly inter-related.

Given only some of the patches were included, it created a situation
where FLOGI's fail, thus SLI Ports can't start communication.

Reverting this patch as its one of the partial Path Split patches
that was included.
