[PATCH] nvmet: Set ctrl->kato to a default NVMET_DISC_KATO value

[Sagi Grimberg]

>>> We want to avoid starting the keep-alive timer with a zero timeout value

>> "This field specifies the timeout value for the Keep Alive feature in

>> Keep Alive Timer is disabled."
>>
>> we should not just set a random high timeout but just disable the

Just noticed its nvmet.

We need an equivalent patch for nvmet, that's all
