[PATCH v4 05/13] media: nxp: imx8-isi: Remove redundant check for dma_set_mask_and_coherent()

[Frank Li]

dma_set_mask_and_coherent() never return failure when mask bigger than
32bit.

See commit f7ae20f2fc4e ("docs: dma: correct dma_set_mask() sample code")

So remove return value check for dma_set_mask_and_coherent().
