ALSA: ac97c: Fix an error handling path in 'atmel_ac97c_probe()' 

If 'clk_prepare_enable()' fails, we must release some resources before
returning. Add a new label in the existing error handling path and 'goto'
there.

Fixes: 260ea95cc0 ("ASoC: atmel: ac97c: Handle return value of clk_prepare_enable.")
