The driver fails to allocate command buffers in the routine
lpfc_new_scsi_buf_s4
There is an inconsistency between lpfc_mem_alloc(), where the
phba->lpfc_sg_dma_buf_pool is created, and lpfc_new_scsi_buf_s4(),
when we allocate a buffer from the pool and check the alignment.
The alignment should be on a page boundary, based on
LPFC_SLI3_BG_ENABLED in sli3_options, for both cases.
Fix by explicitly tracking sli4 vs sli3 and BG options.
The result is that phba->cfg_sg_dma_buf_size is now set correctly
for SLI-4.
