Public bug reported:
1) For NVFS I/Os, blk_rq_nr_phys_segments() can undercount GPU physical
segments since CPU-side segment contiguity may differ from GPU physical
contiguity. This can undersize the SGL pool causing a buffer overrun.
2) nvfs_blk_rq_dma_map_iter_next() can create DMA mappings that exceed
the number of entries that can be stored or subsequently unmapped.
Fix both issues.
