nvmet: reset keep alive timer in controller enable
[ Upstream commit d68a90e148f5a82aa67654c5012071e31c0e4baa ]
Controllers that are not yet enabled should not really enforce keep alive
timeouts, but we still want to track a timeout and cleanup in case a host
died before it enabled the controller. Hence, simply reset the keep
alive timer when the controller is enabled.
