Tasos Sahanidis 3ad6a6288c media: saa7146: use sg_dma_len when building pgtable
[ Upstream commit e56429b09d5e0802b86f84ec7c24025886c9f88b ]

The new AMD IOMMU DMA implementation concatenates sglist entries under
certain conditions, and because saa7146 accessed the length member
directly, it did not support this scenario.

This fixes IO_PAGE_FAULTs by using the sg_dma_len macro.
