AudioFlinger: device effect not added to HAL 



Regression introduced by checking on assigned io rather
than boolean addedToHAL. Device effects may not be assigned to
an io, hence they are never added to HAL.
This CL fixes by adding relying on an virtual API rather then in io.
Implementations will be specific to device / session effects.
