drm/msm: Ensure mmap offset is initialized
If a GEM object is allocated, and then exported as a dma-buf fd which is
mmap'd before or without the GEM buffer being directly mmap'd, the
vma_node could be unitialized. This leads to a situation where the CPU
mapping is not correctly torn down in drm_vma_node_unmap().
Fixes: e5516553999f ("drm: call drm_gem_object_funcs.mmap with fake offset")
