If all configured routing engines fail to initialize, the routing engine
list will be empty. If opensm is also configured for no fallback routing
engine, then osm_ucast_mgr_process() can incorrectly return success even
though no routing engine will run. The result of that is that heavy
sweeps are attempted in a tight loop, spamming opensm logs and the fabric.
With this fix, heavy sweeps occur only after a trap or the sweep interval,
reducing log spam and making it easier to find the reason for the failure.
