If 'devm_kstrdup()' fails, we should return -ENOMEM.
While at it, move the 'of_node_put()' call in the error handling path and
after the 'machine' has been copied.
Better safe than sorry.

Not sure of which Fixes tag to add. Should be a6fc3b698130, but since
another commit needs to be reverted for this patch to make sense, I'm
unsure of what to do. :(
So, none is given.
