selftests: Fix the if conditions of in test_extra_filter()

BugLink: https://bugs.launchpad.net/bugs/1995517
[ Upstream commit bc7a319844891746135dc1f34ab9df78d636a3ac ]

The socket 2 bind the addr in use, bind should fail with EADDRINUSE. So
if bind success or errno != EADDRINUSE, testcase should be failed.
