clk_prepare_enable() is called instead of clk_disable_unprepare() in the
error handling path of the probe function.

Change the function that is called so that resources are released
correctly.

Hey Christophe,
Peng Wu already sent a patch for this, but thanks for trying
to clean up after me anyway.
Thanks,
Conor.
