mmc: core: quirks: Add of_node_put() when breaking out of loop

Browse Source 
[ 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.

Fixes: b360b1102670 ("mmc: core: allow to match the device tree to apply quirks")
