dmaengine: mv_xor: fix child node refcount handling in early exit
commit 362f1bf98a3ecb5a2a4fcbdaa9718c8403beceb2 upstream.
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.
