From: Max Reitz <mre...@redhat.com>
The only caller of bdrv_close() left is bdrv_delete(). We may as well
assert that, in a way (there are some things in bdrv_close() that make
more sense under that assumption, such as the call to
bdrv_release_all_dirty_bitmaps() which in turn assumes that no frozen
bitmaps are attached to the BDS).
In addition, being called only in bdrv_delete() means that we can drop
bdrv_close()'s forward declaration at the top of block.c.
