spi: airoha: switch back to non-dma mode in the case of error
[ Upstream commit 20d7b236b78c7ec685a22db5689b9c829975e0c3 ]
Current dirmap code does not switch back to non-dma mode in the case of
error. This is wrong.
This patch fixes dirmap read/write error path.
Fixes: a403997c12019 ("spi: airoha: add SPI-NAND Flash controller driver")
