drm/amd/display: remove dpp pipes on failure to update pipe params
[why]
There are cases where update pipe params could fail but dpp pipes are already
added to the state. In this case, we should remove dpp pipes so dc state is
restored back. If it is not restored, dc state is corrupted after calling this
function, so if we call the same interface with the corrupted state again, we
may end up programming pipe topology based on a corrupted dc state.
