Subject: mlxsw: spectrum: Reduce dependency between bridge and router code
Patch-mainline: v5.7-rc1
Git-commit: da1f9f8cb75c3506e7dedb4cb2221fe5dd4c52b7
References: bsc#1176774

Commit f40be47a3e40 ("mlxsw: spectrum_router: Do not force specific
configuration order") added a call from the routing code to the bridge
code in order to handle the case where VNI should be set on a FID
following the joining of the router port to the FID.

This is no longer required, as previous patches made VXLAN devices
explicitly take a reference on the FID and set VNI on it.

Therefore, remove the unnecessary call and simply have the RIF take a
reference on the FID without checking if VNI should also be set on it.
