tests: Make ap_wps_er_http_proto less likely to fail

The test step for concurrent HTTP connections seems to be failing quite
frequently when running in a virtual machine with run-tests.py (but not
that much with kvm and vm-run.sh). The failures are due to only 8 or 9
sockets getting a response from the HTTP server. This is sufficient for
testing purposes, to drop the pass criterium from 10 to 8 concurrent
connections. This avoids unnecessary test failures and also allows the
rest of the test case to be performed.
