block/block-copy: move copy_bitmap initialization to block_copy_state_new()
We are going to complicate bitmap initialization in the further commit. And in future, backup job will be able to work without filter (when source is immutable), so we'll need same bitmap initialization in copy-before-write filter and in backup job. So, it's reasonable to do it in block-copy. Note that for now cbw_open() is the only caller of block_copy_state_new().
