util.adminstream: Fix traceback on double-close (fixes #1913) In some circumstances, particularly with 'opportunistic_writes' and 'fatal_errors' enabled in the epoll backend, the connection may be closed halfway through the session close process (because it contains debug logging, which in the case of the watch:log() command, will trigger a write to the socket). The chosen fix is to cache session.conn in a local variable (we already did this later on, but this pulls it up to the top of the function, which is generally more correct anyway).
