drm/amd/display: Guard against invalid array access
[Why]
There are scenarios where no OPP is assigned to an OTG so its value is
0xF which is outside the size of the OPP array causing a potential
driver crash.
[How]
Change the assert to an early return to guard against access. If
there's no OPP assigned already, then OTG will be blank anyways so no
functionality should be lost.
