msm: kgsl: don't clear gpuaddr when unmapping global mappings
Memory mapped through kgsl_mmu_map_global() is supposed to have
the same gpu address in all pagetables. And the memdesc will
persist beyond the lifetime of any single pagetable.
Therefore, memdesc->gpuaddr should not be zeroed for these
memdescs.
