gtpu: Track the dst FIB entry instead of RR sourcing that
RR sourcing the destination FIB entry limits the number of tunnels to 255 for a particular destination. This change removes this limit. Type: fix The patch is based on 1f50bf8fc57ebf78f9056185a342493be460a847 that introduced the FIB entry tracking but did not update the gtpu plugin.
