[PATCH 4/5] scripts/device-crash-test: don't emit AQMP connection errors to stdout

[John Snow <jsnow@redhat.com>]

These errors are expected, so they shouldn't clog up terminal output. In
the event that they're *not* expected, we'll be seeing an awful lot more
output concerning the nature of the failure.
