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.
