spi: dw: restore previous irq handling behavior when !ctlr->cur_msg
Recent "enhanced" support changes the dw_spi_irq() behavior a bit
when !!ctlr->cur_msg:
if (!ctlr->cur_msg && dws->transfer_handler == dw_spi_transfer_handler) {
dw_spi_mask_intr(dws, 0xff);
return IRQ_HANDLED;
}
But it misses the dma case, where the transfer_handler ==
dw_spi_dma_transfer_handler, so this changes the previous long time
working behavior, let's restore the previous handling by only filtering
out the dw_spi_enh_handler.
