i40e: add check for null VSI

Return from i40e_vsi_reinit_setup() if vsi param is NULL.
This makes this code consistent with all the other code that
checks for NULL before using one of the VSI pointers accessed
with an indexed variable. (Indexed VSI pointers are
intentionally set to NULL in i40e_vsi_clear() and
i40e_remove().
