Subject: [PATCH] ASoC: codecs: Fix an error handling path in va_macro_probe()

After a successful lpass_macro_pds_init() call, lpass_macro_pds_exit() must
be called.

Add the missing call in the error handling path of the probe function and
use it.

Fixes: 9e3d83c52844 ("ASoC: codecs: Add power domains support in digital macro codecs")
