block-migration: add lock
Some state is shared between the block migration code and its AIO callbacks. Once block migration will run outside the iothread, the block migration code and the AIO callbacks will be able to run concurrently. Protect the critical sections with a separate lock. Do the same for completed_sectors, which can be used from the monitor.
