[PATCH 1/2] qemu: fix qemuMigrationSrcCleanup to use qemuMigrationJobFinish

[Nikolay Shirokovskiy <nshirokovskiy@xxxxxxxxxxxxx>]

qemuMigrationSrcCleanup uses qemuDomainObjDiscardAsyncJob currently. But
discard does not reduce jobs_queued counter so it leaks. Also discard does not
notify other threads that job condition is available. Discard does reset nested
job but nested job is not possible in this conditions.
