sfc: Include XDP packet headroom in buffer step size.

Correct a mismatch between rx_page_buf_step and the actual step size
used when filling buffer pages.

This patch fixes the page overrun that occured when the MTU was set to
anything bigger than 1692.

Fixes: 3990a8fffbda ("sfc: allocate channels for XDP tx queues")
