MLK-11911-5 mxc IPUv3: pixel clk: Free gate clk memory if clk_regiser fails

This patch fixes the following issue reported by Coverity:
	if (IS_ERR(clk))
freed_arg: kfree frees clk. [Note: The source code implementation of the
function has been overridden by a builtin model.]
		kfree(clk);

Use after free (USE_AFTER_FREE)
use_after_free: Using freed pointer clk.
	return clk;
