block: fix bdrv_flush() ordering in bdrv_close()
Since 80ccf93b we flush the block device during close. The
bdrv_drain_all() call should come before bdrv_flush() to ensure guest
write requests have completed. Otherwise we may miss pending writes
when flushing.
Call bdrv_drain_all() again for safety as the final step after
bdrv_flush(). This should not be necessary but we can be paranoid here
in case bdrv_flush() left I/O pending.
