scsi: megaraid_mbox: remove bogus use of pci_dma_sync_sg_* APIs
The dma_map_sg / dma_unmap_sg APIs called from scsi_dma_map /
scsi_dma_unmap already transfer memory ownership to the device or cpu
respectively. Adding additional calls to pci_dma_sync_sg_* will in fact
lead to data corruption if we end up using swiotlb for some reason.
Also remove the now pointless megaraid_mbox_sync_scb function.
