spi: pxa2xx: update outdated reference to pump_transfers()

The function pump_transfers() was split into
pxa2xx_spi_transfer_one(), pxa2xx_spi_handle_err() and
pxa2xx_spi_set_cs() in commit d5898e19c0d7 ("spi: pxa2xx: Use
core message processing loop").  The comment in
pxa2xx_spi_dma_transfer_complete() still warns about concurrent
calls to pump_transfers(), but the actual operation protected by
dma_running is now spi_finalize_current_transfer().  Update the
reference.
