net: dsa: lantiq_gswip: Fix refcount leak in gswip_gphy_fw_list
[ Upstream commit 0737e018a05e2aa352828c52bdeed3b02cff2930 ]
Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node.
when breaking early from a for_each_available_child_of_node() loop,
we need to explicitly call of_node_put() on the gphy_fw_np.
Add missing of_node_put() to avoid refcount leak.
Fixes: 14fceff4771e ("net: dsa: Add Lantiq / Intel DSA driver for vrx200")
