ASoC: da7219: Fix an error handling path in da7219_register_dai_clks()
[ Upstream commit abb4e4349afe7eecdb0499582f1c777031e3a7c8 ]
If clk_hw_register() fails, the corresponding clk should not be
unregistered.
To handle errors from loops, clean up partial iterations before doing the
goto. So add a clk_hw_unregister().
Then use a while (--i >= 0) loop in the unwind section.
