virutil: introduce helper functions for memory limits
The first one is to truncate the memory limit to VIR_DOMAIN_MEMORY_PARAM_UNLIMITED if the value is greater and the second one is to decide whether the memory limit is set or not, unlimited means that it's not set. Signed-off-by: Pavel Hrdina <phrdina@redhat.com>
