[PULL 2/7] replication: assert we own context before job_cancel_sync

[Kevin Wolf]

From: Stefan Reiter <address@hidden>

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).

In this case we're in a BlockDriver handler, so we already have a lock,
just assert that it is the same as the one used for the commit_job.
