nvmet-fc: abort command when there is no binding 



[ Upstream commit 3146345c2e9c2f661527054e402b0cfad80105a4 ]

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.
