napatech: Close streams on hard errors

Issue: 5172

This commit forces the current stream to be closed when a hard error
occurs.

Without this commit, a hard error will force a 2nd connection
the stream that raised the error.

With this commit, the stream with the hard error is closed before
opening another connection to the stream.

Verified with the Python snippet in the redmine issue.
