mmc: core: quirks: Add of_node_put() when breaking out of loop
[ Upstream commit 883c1d6fa4368a63cae2d6ae2d9c91141c60e233 ]
In mmc_fixup_of_compatible_match(), we should call of_node_put()
when breaking out of for_each_child_of_node() which will increase
and decrease the refcount during one iteration.
