Audio Effects: fix problems in volume control.

- Fixed click when re-enabling effect during the turn off phase:
make sure the effect states where effect is processed are the same
where volume control is delegated to effect.
- Fixed click when effect is deleted while still active: do not apply
volume ramp if an effect having volume control was just removed from the
effect chain.

Also fixed a crash when PCM dump is enabled in effect bundle wrapper.
