block: move drain outside of bdrv_set_backing_hd_drained()
This is part of resolving the deadlock mentioned in commit "block:
move draining out of bdrv_change_aio_context() and mark GRAPH_RDLOCK".
The function bdrv_set_backing_hd_drained() holds the graph lock, so it
is not allowed to drain. It is called by:
1. bdrv_set_backing_hd(), where a drained section is introduced,
replacing the previously present bs-specific drains.
2. stream_prepare(), where a drained section is introduced replacing
the previously present bs-specific drains.
The drain_bs variable in bdrv_set_backing_hd_drained() is now
superfluous and thus dropped.
