[Freedreno] [PATCH v3 7/7] drm/msm/dpu: _dpu_plane_get_aspace returns

[Bruce Wang]

Remove unneeded checks from _dpu_plane_get_aspace. The function
no longer needs to return anything so it is changed to void.

v3: Made return value of function struct msm_gem_address_space* instead
of passing one in to reflect the purpose of the function.
