Merged revisions 1431171 from tomcat/trunk:
Fix release of processors in AjpNioProtocol. Wrong object was used as a key in the connections map.

"connections" is "Map<S,Processor<S>>". The key in the map is socket, not its wrapper.

Found this in a review inspired by a similar fix in r1426662.
(r1426662 itself is specific to Tomcat 8 and does not need a backport).
