This patch changes the length variables from unsigned int to size_t. Using size_t ensures that we can handle larger sizes, as size_t is always equal to or larger than the previously used u32 type. Originally, u32 was used because blk-mq-dma code evolved from scatter-gather implementation, which uses unsigned int to describe length. This change will also allow us to reuse the existing struct phys_vec in places that don't need scatter-gather.
