net: sched: provide shim definitions for taprio_offload_{get,free}

Browse Source 
All callers of taprio_offload_get() and taprio_offload_free() prior to
the blamed commit are conditionally compiled based on CONFIG_NET_SCH_TAPRIO.

felix_vsc9959.c is different; it provides vsc9959_qos_port_tas_set()
even when taprio is compiled out.

Provide shim definitions for the functions exported by taprio so that
felix_vsc9959.c is able to compile. vsc9959_qos_port_tas_set() in that
case is dead code anyway, and ocelot_port->taprio remains NULL, which is
fine for the rest of the logic.

Fixes: 1c9017e44a ("net: dsa: felix: keep reference on entire tc-taprio config")
