[PATCH v2] drm/msm/dpu: simplify and unify dpu_encoder_get_intf and dpu_encoder_get_wb

[Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>]

Remove extra nestting level from the dpu_encoder_get_intf(), replacing it
with the explicit return in case the INTF_WB was passed to the function.

While we are at it, also change dpu_encoder_get_wb() to also use
explicit return rather than the goto.
