[PATCH -next] drm/msm: Remove unused variables 'top'

[Chen Zhongjin]

'commit 1e5df24b996c ("drm/msm/dpu: drop length from struct dpu_hw_blk_reg_map")'
'commit 9403f9a42c88 ("drm/msm/dpu: merge base_off with blk_off in struct dpu_hw_blk_reg_map")'
These commits had merged hw.blk_off and hw.blk_off to mdp.
So we don't need to get dpu_hw_mdp in dpu_kms_mdp_snapshot() now.

Since there is no code using 'top' in this function. Remove it.
