Add error handling of CloseWrite()

Browse Source 
The e2e test "Kubectl Port forwarding With a server listening .."
is failed sometimes due to the difference between expected data and
received data. To receive the data, the test does CloseWrite() but
it didn't have the corresponding error handling.
This adds it to investigate the issue more.
