[Qemu-block] [PATCH] block: all I/O should be completed before removing throttle timers.

From: Zhengui In blk_remove_bs, all I/O should be completed before removing throttle timers. If there has inflight I/O, removing throttle timers here will cause the inflight I/O never return. This patch add bdrv_drained_begin before throttle_timers_detach_aio_context to let
