scsi: mvsas: Fix dma_unmap_sg() nents value
[ Upstream commit 0141618727bc929fe868153d21797f10ce5bef3f ]
The dma_unmap_sg() functions should be called with the same nents as the
dma_map_sg(), not the value the map function returned.
Fixes: b5762948263d ("[SCSI] mvsas: Add Marvell 6440 SAS/SATA driver")
