nvmet-auth: take only AUTH_Negotiate for a negotiation

nvmet_execute_auth_send() hands a common-type message to
nvmet_auth_negotiate() if its ID is AUTH_Negotiate or matches the step
the queue is in. The second case is wrong: the only other common-type
message a host sends is AUTH_Failure2, and no queue waits in that step.
A host can name the step on purpose though, and its message is then
treated as a new AUTH_Negotiate without the work that goes with a new
transaction, like reloading the keys on the admin queue.

Fail every other common-type message, as AUTH_Failure2 already is.
