output/alsa: remove period_time adjust loop

This loop was introduced in commit 24c1f463, but -EPIPE is not a possible error condition for snd_pcm_hw_params(). This code does not appear to make sense. Problems with a wrong period_time should be caught before that by snd_pcm_hw_params_set_period_time_near(). This commit removes the last "goto" in MPD! Yay!
