poemgr: sleep through race condition regarding input type #3

Thanks for this driver, tool and package :-)

The PoE chip might need a tiny moment before input detection. On a USW-Flex powered by an 802.3at injector (TL-POE160S), it initially reports a 802.3af input, which results in a low-balled power budget. After the following small nap, input is correctly read as 802.3at.

The low-balled power budget can be an actual problem. Example: the downstream PoE consumer is an 802.3af-to-passive converter (INS-3AF-O-G) which reports its maximum power draw of 12.6 W although the actual draw is much lower. That means without this fix, one little consumer device already exceeds the configured power budget.

Thanks. I've fixed up the comment style locally and pushed it to master.
