block: mark bdrv_close() as GRAPH_UNLOCKED
The functions blk_log_writes_close(), blkverify_close(),
quorum_close(), vmdk_close() via vmdk_free_extents(), and other
bdrv_close() implementations call bdrv_graph_wrlock_drained(), which
must be called with the graph unlocked. They are reached via the
BlockDriver's bdrv_close() callback and the bdrv_close() wrapper,
which are also marked as GRAPH_UNLOCKED_PTR and GRAPH_UNLOCKED.
Furthermore, the function bdrv_close() also calls bdrv_drained_begin()
and bdrv_graph_wrlock_drained(), so there are additional reasons for
marking it GRAPH_UNLOCKED.
