dmaengine: mediatek: mtk-hsdma: Fix a resource leak in the error handling path of the probe function
commit33cbd54dc5
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
