Subject: [PATCH] qemu_migration: Acquire correct job in
qemuMigrationSrcIsAllowed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit 62627524607f added the acquiring of a job, but it is not always
VIR_ASYNC_JOB_MIGRATION_OUT, so the code fails when doing save or anything else.
Correct the async job by passing it from the caller as another parameter.
