drm/msm/dpu: Remove unneeded checks in dpu_plane.c
Removes some checks from dpu_plane.c that will never result in an error. Subsequent variable assignments become part of the initialization wherever possible. Unused variables are removed. v3: removed additional impossible checks and called helper function _dpu_plane_get_kms() where possible.
