[PATCH] ASoC: codecs: lpass-va-macro: Propagate regcache_sync() errors

[Pengpeng Hou]

va_macro_runtime_resume() enables clocks, leaves cache-only mode, and
replays cached register state. It currently ignores regcache_sync()
failures and can report success.

Propagate sync failures, restore cache-only/dirty state, and unwind
clocks enabled by the resume path.
