clk: imx: imx8mq: correct error handling path
Avoid memory leak in error handling path. It does not make
much sense for the SoC without clk driver, to make program behavior
correct, let's fix it.
Fixes: b80522040cd3 ("clk: imx: Add clock driver for i.MX8MQ CCM")
Reported-by: kernel test robot <lkp@intel.com>
Reported-by: Dan Carpenter <error27@gmail.com>
