[PATCH v4 2/3] replication: acquire aio context before calling job_cancel_sync

[Stefan Reiter <s.reiter@proxmox.com>]

job_cancel_sync requires the job's lock to be held, all other callers
already do this (replication_stop, drive_backup_abort,
blockdev_backup_abort, job_cancel_sync_all, cancel_common).
