Remove 'inconnect' Connection flag

There are cases when this flag is not set appropriately, that lead to a
reconnection stuck: at least the case that was fixed in the commit 'Fix
stuck autoreconnect case'.

To more on that, this flag was only needed to workaround Windows-related
bug with broken socket liveness check. Now it is fixed, so it is safe to
remove it.

Fixes #108.
