block: all I/O should be completed before removing throttle timers.
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 all I/O completed before removing throttle timers.
[Moved declaration of bs as suggested by Alberto Garcia
<berto@igalia.com>.
