clk: imx: scu: Fix memory leak in __imx_clk_gpr_scu()
In cases where imx_clk_is_resource_owned() returns false, the code path
does not handle the failure gracefully, potentially leading to a memory
leak. This fix ensures proper cleanup by freeing the allocated memory
for 'clk_node' before returning.
