Currently when FidoDevice fails on AuthenticatorGetInfo command, we
assume that the device supports U2F protocol and initiate U2F request.
Prior to initiating request, check whether AuthenticatorGetInfo command
failed due to any device communication error. If the failure was caused
by device error, drop remaining requests on the device. Also, to prevent
similar failures, always check for device state before dispatching
consecutive requests to authenticators.
