ASoC: codecs: lpass: Fix passing zero to 'PTR_ERR'

sound/soc/codecs/lpass-macro-common.c:28 lpass_macro_pds_init() warn: passing zero to 'PTR_ERR'
sound/soc/codecs/lpass-macro-common.c:38 lpass_macro_pds_init() warn: passing zero to 'PTR_ERR'
sound/soc/codecs/lpass-macro-common.c:54 lpass_macro_pds_init() warn: passing zero to 'ERR_PTR'

dev_pm_domain_attach_by_name() may return NULL, set 'ret' as
-ENODATA to fix this warning.
