[dpdk-dev] [PATCH v2] i40e: dereference before null check

Fix issue reported by Coverity.
Coverity ID 13302:
There may be a null pointer dereference, or else the comparison against
null is unnecessary.

In i40evf_config_vlan_pvid: All paths that lead to this null pointer
comparison already dereference the pointer earlier

Fixes: 2b12431b5369 ("i40e: add vlan stripping and insertion to VF")
