ccr reuses the control queue and first rx queue from the first port on
each adapter. The driver cannot send requests until those queues are
initialized. Refuse to create sessions for now if the queues aren't
ready. This is a workaround until cxgbe allocates one or more
dedicated queues for ccr.

• kldload ccr and cryptodev and run cryptocheck -d ccr0. Previously panicked, now fails with ENXIO.
• do ifconfig cc0 up and verify that cryptocheck still works.
