Avoid to call create_disks if we update an existing disk.

If I understand, the only case we need to call it, is if we update an existing disk by a different disk, or reassign an unused disk ?

something like that:

if(!$old_drive->{file} || $drive->{file} ne $old_drive->{file}){

    &$create_disks($rpcenv, $authuser, $conf, $storecfg, $vmid, undef, {$opt => $value});
}

AFAIK we only call that if someone want to add an existing volid. In that case we need to activate the volid, 
and check if the volume really exists. 

What do you want to avoid exactly?
