ASoC: core: Don't schedule deferred_resume_work twice
commit 82e14e8bdd88b69018fe757192b01dd98582905e upstream. For cards that have two or more DAIs, snd_soc_resume's loop over all DAIs ends up calling schedule_work(deferred_resume_work) once per DAI. Since this is the same work item each time, the 2nd and subsequent calls return 0 (work item already queued), and trigger the dev_err message below stating that a work item may have been lost. Solve this by adjusting the loop to simply calculate whether to run the resume work immediately or defer it, and then call schedule work (or not) one time based on that. Note: This has not been tested in mainline, but only in chromeos-2.6.38; mainline doesn't support suspend/resume on Tegra, nor does the mainline Tegra ASoC driver contain multiple DAIs. It has been compile-checked in mainline.
