Subject: mlxsw: spectrum_router: Move mlxsw_sp_rif_ipip_lb_op()
Patch-mainline: v4.16
Git-commit: 22b99058dd79ecff9de64eb30e15a330d89862c6
References: bsc#1112374

Move the function so that it can be called without forward declaration
from a function that will be added in a follow-up patch.

Fixes: 0063587d3587 ("mlxsw: spectrum: Support decap-only IP-in-IP tunnels")
