fix pbe/haas surround dsps: surround_enabled, redo flush functions.

Browse source 
surround_enabled was never true, end up dsp_surround_flush didn't work; Thats why a cracking noise occurs in right channel when moving track positions.

redo pbe/surround flush in a much simpler way suits the current single buffer style.
