commit 0257ba8f9f4bf522a106aa2bbb4756e391a3dd42

Use max bandwidth from qemuDomainObjPrivate struct when migrating
    
    Adjust qemuMigrationRun() to use migMaxBandwidth in qemuDomainObjPrivate
    structure when setting qemu migration speed.  Caller-specified 'resource'
    parameter overrides migMaxBandwidth.
