dmaengine: mediatek: hsdma_probe: fixed a memory leak when devm_request_irq fails

Browse source 
[ Upstream commit 1ff95243257fad07290dcbc5f7a6ad79d6e703e2 ]

When devm_request_irq fails, currently, the function
dma_async_device_unregister gets called. This doesn't free
the resources allocated by of_dma_controller_register.
Therefore, we have called of_dma_controller_free for this purpose.
