Subject: [PATCH] Remove extra checks to fix #9456 (#9523)

Motivation:

There are some extra log level checks (logger.isWarnEnabled()).

Modification:

Remove log level checks (logger.isWarnEnabled()) from io.netty.channel.epoll.AbstractEpollStreamChannel, io.netty.channel.DefaultFileRegion, io.netty.channel.nio.AbstractNioChannel, io.netty.util.HashedWheelTimer, io.netty.handler.stream.ChunkedWriteHandler and io.netty.channel.udt.nio.NioUdtMessageConnectorChannel

Result:

Fixes #9456
