SPARK-1478.2 Fix incorrect NioServerSocketChannelFactory constructor …

…call

The line break inadvertently means this was interpreted as a call to the no-arg constructor. This doesn't exist in older Netty even. (Also fixed a val name typo.)

Closes apache#1466 from srowen/SPARK-1478.2 and squashes the following commits:
