i40e: fix potential NULL pointer dereferencing of pf->vf i40e_sync_vsi_filters()

Browse source

[ Upstream commit 9525a3c38a ]

Add check for pf->vf not being NULL before dereferencing
pf->vf[vsi->vf_id] in updating VSI filter sync.
Add a similar check before dereferencing !pf->vf[vsi->vf_id].trusted
in the condition for clearing promisc mode bit.
