Cache SelectorProvider is not suitable for NioServerSocketChannel

See original GitHub issue

I found the issue https://github.com/netty/netty/issues/2308 saying that calling SelectorProvider#provider for every new channel creation causes performance problems，So the SelectorProvider is cached. But cache SelectorProvider is not suitable for NioServerSocketChannel, because NioServerSocketChannel will only be created once, it will not be created many times like NioSocketChannel, caching SelectorProvider in NioServerSocketChannel is instead a memory consumption.

How does it cause unnecessary memory overhead when it is a static field?
