dmaengine: xilinx_dma: Report error in case of dma_set_mask_and_coherent API failure
The driver does not handle the failure case while calling
dma_set_mask_and_coherent API.
In case of failure, capture the return value of API and then report an
error.
Addresses-coverity: Unchecked return value (CHECKED_RETURN)
