hgclient: look for an open server before closing it in ResponseError block

At least some of the codepaths that can throw a ResponseError close
the server first (the one in _readchannel does so in order to detect
server startup failures, for example), so we have to verify we have a
server to close before doing so, otherwise we can lose the
ResponseError and the user sees an AttributeError when we try to use
.close() on a NoneType.
