dmaengine: xilinx_dma: check dma_async_device_register return value 



dma_async_device_register() can return non-zero error code. Add
condition to check the return value of dma_async_device_register
function and handle the error path.

Addresses-Coverity: Event check_return.
Fixes: 9cd4360d ("dma: Add Xilinx AXI Video Direct Memory Access Engine driver support")
