MINOR: backend: Remove test on HTX streams to reuse idle connections on connect

In connect_server() function, there is a test to be able to reuse idle
connections for HTX streams only. Till now, only HTTP connections can be
idle. And this tests was added to be sure to now reuse idle connections for
legacy HTTP streams. But the legacy HTTP was removed in HAProxy-2.1. So we
can safely remove this test.

The related issue is #2502.
