net/mlx5e: Use runtime page_shift for striding RQ
This commit allows striding RQ to determine MTT page size at runtime, instead of sticking to the compile-time PAGE_SIZE. This functionality will be used by a following commit that adjusts the MTT page size to the XSK frame size. Stick with PAGE_SIZE for XSK on legacy RQ, as frag_stride is not used in data path, it only helps calculate how pages are partitioned into fragments, and PAGE_SIZE will ensure each fragment starts at the beginning of a new allocation unit (XSK frame).
