clk: st: clk-flexgen: Add of_node_put() in st_of_flexgen_setup()
In function st_of_flexgen_setup, variable pnode takes the return value of of_get_parent, which gets a node but does not put it. If pnode is not put before the function returns, it may cause a memory leak. Hence put pnode after its last occurrence. Issue found with Coccinelle.
