dmaengine: mediatek: mtk-hsdma: Fix a resource leak in the error handling path of the probe function 

commit 33cbd54dc5 upstream.

'mtk_hsdma_hw_deinit()' should be called in the error handling path of the
probe function to undo a previous 'mtk_hsdma_hw_init()' call, as already
done in the remove function.

Fixes: 548c4597e9 ("dmaengine: mediatek: Add MediaTek High-Speed DMA controller for MT7622 and MT7623 SoC")
