dmaengine: Revert "dmaengine: add verification of DMA_INTERRUPT capability for dmatest"

This reverts commit a8facc7b9885 ("dmaengine: add verification of
DMA_INTERRUPT capability for dmatest") as it causes regression due to
the fact that DMA_INTERRUPT in linked to dma_prep_interrupt() so
checking that is incorrect here
