dmaengine: mmp_pdma: fix reference count leaks in mmp_pdma_probe
The issue happens in an error handling path. If
of_dma_controller_register() fails, the function simply prints error
messages and returns error code, without decrementing the reference
count of pdev->device incremented earlier by
dma_async_device_register(), which may result in refcount leaks.
Fix it by invoking dma_async_device_unregister() before returning the
error code.
