crypto: ccp - Remove manual check and set of dma_mask pointer
The underlying device support will set the device dma_mask pointer if DMA is set up properly for the device. Remove the check for and assignment of dma_mask when it is null. Instead, just error out if the dma_set_mask_and_coherent function fails because dma_mask is null.
