similar cleanup is also needed in nvmet_execute_auth_receive(),
in general nvmet_execute_auth_receive() and nvmet_execute_auth_send()
has a lot of common code that can use cleanup, I've a series on the
top of this one ..

but prior to that we need these two patches to make both functions
close enough so I can send a final cleanup on the top of this ..
