Shlomo Pongratz a664a4f7aa net/ipv4: Use proper RCU APIs for writer-side in udp_offload.c ...

RCU writer side should use rcu_dereference_protected() and not
rcu_dereference(), fix that. This also removes the "suspicious RCU usage"
warning seen when running with CONFIG_PROVE_RCU.

Also, don't use rcu_assign_pointer/rcu_dereference for pointers
which are invisible beyond the udp offload code.

Fixes: b582ef0 ('net: Add GRO support for UDP encapsulating protocols')
