commit 29605313104a621de0a28322be95a0398f47d86e

qemu: qemuDomainSetLaunchSecurityState: do not lookup qemuCaps in cache
    
    Any active domain has a copy in the privateData, filled in
    qemuProcessInit.
    
    Move the qemu capability check below the activeness check and remove
    the extra lookup.
