Introduce i40e_for_each_vsi() and i40e_for_each_veb() helper
macros and use them to iterate relevant arrays.
Replace pattern:
for (i = 0; i < pf->num_alloc_vsi; i++)
by:
i40e_for_each_vsi(pf, i, vsi)
and pattern:
for (i = 0; i < I40E_MAX_VEB; i++)
by
i40e_for_each_veb(pf, i, veb)
These macros also check if array item pf->vsi[i] or pf->veb[i]
are not NULL and skip such items so we can remove redundant
checks from loop bodies.

It would be safer to update idx to index of returned vsi in
__i40e_pf_next_vsi() so
(pf->vsi[i] == vsi) in i40e_pf_for_each_vsi(pf, i, vsi) loop.
Will fix this in v5.
Thanks,
Ivan
