i40e: Fix waiting for queues of all VSIs to be disabled

[ Upstream commit c73729b64bb692186da080602cd13612783f52ac ]

The function i40e_pf_wait_queues_disabled() iterates all PF's VSIs
up to 'pf->hw.func_caps.num_vsis' but this is incorrect because
the real number of VSIs can be up to 'pf->num_alloc_vsi' that
can be higher. Fix this loop.
