From: Dmytro Laktyushkin <Dmytro.Laktyushkin@xxxxxxx>
An earlier change added update of interdependent dlg/ttu params for pipes
not being updated in the current call. The code fails to check if the other
pipes are actually active yet causing an assert.
This change adds a check for surface presence on the pipes before updating
the interdepenednt params.
