drm/shmem-helper: Fix locking for drm_gem_shmem_get_pages_sgt()
Other functions touching shmem->sgt take the pages lock, so do that here
too. drm_gem_shmem_get_pages() & co take the same lock, so move to the
_locked() variants to avoid recursive locking.
Discovered while auditing locking to write the Rust abstractions.
Fixes: 2194a63a818d ("drm: Add library for shmem backed GEM objects")
Fixes: 4fa3d66f132b ("drm/shmem: Do dma_unmap_sg before purging pages")
