CHROMIUM: ALSA: hda/ca0132 - update latency when dsp effect changes

Before this change, latency value is determined at the
time when a stream was created. Now the latency value gets
updated in ca0132_effects_set() when effects setting has
changed.

BUG=chrome-os-partner:12926
TEST=Manual run looptest tool with debug log to monitor capture &
playback latency value. Can see both latency value changes in realtime
according to 'CrystalVoice' and 'Playback Enhancement' toggles.
