block: check bdrv_in_use() before blockdev operations
Long-running block operations like block migration and image streaming
must have continual access to their block device. It is not safe to
perform operations like hotplug, eject, change, resize, commit, or
external snapshot while a long-running operation is in progress.
This patch adds the missing bdrv_in_use() checks so that block migration
and image streaming never have the rug pulled out from underneath them.
