i40e: Fix use-after-free in i40e_client_subtask()

Currently the call to i40e_client_del_instance frees the object
pf->cinst, however pf->cinst->lan_info is being accessed after
the free. Fix this by adding the missing return.

Addresses-Coverity: ("Read from pointer after free")
Fixes: 2540464cc26a ("i40e: Disable iWARP VSI PETCP_ENA flag on netdev down events")
