Dmitry Osipenko 21aa27ddc5 drm/shmem-helper: Switch to reservation lock ...

Replace all drm-shmem locks with a GEM reservation lock. This makes locks
consistent with dma-buf locking convention where importers are responsible
for holding reservation lock for all operations performed over dma-bufs,
preventing deadlock between dma-buf importers and exporters.
