The delayed_work_pending() check before flush_delayed_work() in
soc_free_pcm_runtime() is unnecessary and racy. flush_delayed_work()
is safe to call unconditionally - it is a no-op when no work is
pending. Remove the check.

The original check was added by commit 9c9b65203492 ("ASoC: core:
only flush inited work during free") but delayed_work_pending()
followed by flush_delayed_work() has a time-of-check/time-of-use
window where work can become pending between the two calls.
