block: mark bdrv_reopen_queue() and bdrv_reopen_multiple() as GRAPH_UNLOCKED

Browse Source 
The function bdrv_reopen_queue() can call bdrv_drain_all_begin(),
which must be called with the graph unlocked.

The function bdrv_reopen_multiple() calls bdrv_reopen_prepare() which
must be called with the graph unlocked.

To mark bdrv_reopen_queue() as GRAPH_UNLOCKED, it is necessary to make
the locked section in reopen_backing_file() shorter.
