Using `bs_allocate_and_copy_cluster()` instead of a zero-length write makes it possible to inflate/decouple snapshots, as the writes would fail with -EPERM, because the snapshots are marked as read-only. Additionally, zero-length non-vector requests are now completed immediately. It makes it consistent with the vector path (which already does that) and allows us to use the zero-length reads as a context for cluster copy. Fixes #2028.
