dmaengine: milbeaut-xdmac: Fix a resource leak in the error handling path of the probe function

Browse Source 
commit d645148cc82ca7fbacaa601414a552184e9c6dd3 upstream.

'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.
