Set quantum to infinity for the zone loading task

When we are loading the zones, set the quantum to UINT_MAX, which makes
task_run process all tasks at once.  After the zone loading is finished
the quantum will be dropped to 1 to not block server when we are loading
new zones after reconfiguration.
