dmaengine: milbeaut-xdmac: Fix a resource leak in the error handling path of the probe function
'disable_xdmac()' should be called in the error handling path of the
probe function to undo a previous 'enable_xdmac()' call, as already
done in the remove function.
Fixes: a6e9be055d47 ("dmaengine: milbeaut-xdmac: Add XDMAC driver for Milbeaut platforms")
