i40e: Fix missing rtnl locking when setting up pf switch
[ Upstream commit 956e759d5f8e0859e86b951a8779c60af633aafd ]
A recent change that made i40e use new udp_tunnel infrastructure
uses a method that expects to be called under rtnl lock.
However, not all codepaths do the lock prior to calling
i40e_setup_pf_switch.
Fix that by adding additional rtnl locking and unlocking.
