Subject: [PATCH v4 09/12] nvmet-fc: abort command when there is no binding
Date: Tue, 30 Jan 2024 10:49:35 +0100

When the target port has not active port binding, there is no point in
trying to process the command as it has to fail anyway. Instead adding
checks to all commands abort the command early.
