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.
