Short description

Fix some minor issues reported by Coverity:

  • one useless test due to the condition being always true ;
  • uncaught exception if we ever try to get the handle of a non-established TCP connection which should never happen.

Also remove some code that has been unused since we moved to an event-based logic.

Checklist

  • read the CONTRIBUTING.md document
  • compiled this code
  • tested this code
  • included documentation (including possible behaviour changes)
  • documented the code
  • added or modified regression test(s)

One useless test due to the condition being always true,
and one uncatched exception if we ever try to get the handle of a
non-established TCP connection which should never happen.
Unused code will only get worse with the time, let's not keep it
around.
