Matthew AuldandGreg Kroah-Hartman 8ca949118e drm/amdgpu/dma_buf: fix page_link check ...

[ Upstream commit c0dd8a9253 ]

The page_link lower bits of the first sg could contain something like
SG_END, if we are mapping a single VRAM page or contiguous blob which
fits into one sg entry. Rather pull out the struct page, and use that in
our check to know if we mapped struct pages vs VRAM.
