Revert "msm: kgsl: Call dma_buf_unmap_attachment() early"

Browse source 
This reverts msm-5.10 commit b84bd97e37f8ac3a0f3194ebcbb1fa962e42cd73.

Warnings for direct dma clients during cache operations are now being
handled by dma-buf driver. Instead of doing dma_buf_unmap_attachment
early if we do it in destroy path, it helps in saving cycles and
improving performance during app launch.
