spi: dw-mid: check that DMA was inited before exit
commit 63d84b1a46957b3ecc56af8087220c0df42e0ef2 upstream.
commit fb57862ead652454ceeb659617404c5f13bc34b5 upstream.
If the driver was compiled with DMA support, but DMA channels weren't acquired
by some reason, mid_spi_dma_exit() will crash the kernel.
Fixes: 7063c0d942a1 (spi/dw_spi: add DMA support)
