qemuProcessReconnect: clear 'oldjob'

Browse Source 
After we started copying the privateData pointer in
qemuDomainObjRestoreJob, we should also free them
once we're done with them.

Register the clear function and use g_auto.
Also add a check for job->cb to qemuDomainObjClearJob,
to prevent freeing an uninitialized job.
