qemu: Use qemuDomainCheckABIStability where needed

Browse Source 
Most places which want to check ABI stability for an active domain need
to call this API rather than the original
qemuDomainDefCheckABIStability. The only exception is in snapshots where
we need to decide what to do depending on the saved image data.
