rGef3f98ae4778: cxgbe: Only run ktls_tick when NIC TLS is enabled.

Summary

Previously the body of ktls_tick was a nop when NIC TLS was disabled,
but the callout was still scheduled consuming power on otherwise-idle
systems with Chelsio T6 adapters. Now the callout only runs while NIC
TLS is enabled on at least one interface of an adapter.
