gpu: nvgpu: remove dead function gk20a_gmmu_unmap

While fixing sparse warning:
- $TOP/kernel/nvgpu/drivers/gpu/nvgpu/gk20a/mm_gk20a.c:2586:6:
 warning: symbol 'gk20a_gmmu_unmap' was not declared. Should it be static?
when gk20a_gmmu_unmap() is made static
compiler complained that it is not used.
Hence removing the unused function.
