drm/amd/display: fix surface update sequence
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.
