napatech: Close streams on hard errors

[jlucovsky]

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. 5172
