qtest: Don't reset on qtest chardev connect

libqtest's qtest_init() connecting to the qtest socket triggers reset.
This was coded in the hope we could use the same QEMU process for
multiple tests that way.  Never used.  Injects an extra reset even
when it's not used, and that can mess up tests such as the one of
-boot once I'm about to add.  Drop it.
