dmaengine: mv_xor: fix child node refcount handling in early exit

Browse Source 
The for_each_child_of_node() loop requires explicit calls to
of_node_put() to decrement the child's refcount upon early exits (break,
goto, return).

Add the missing calls in the two early exits before the goto
instructions.
