ethernet: intel: fix building with large NR_CPUS

[ Upstream commit 24171a5a4a952c26568ff0d2a0bc8c4708a95e1d ]

With large values of CONFIG_NR_CPUS, three Intel ethernet drivers fail to
compile like:

In function ‘i40e_free_q_vector’,
    inlined from ‘i40e_vsi_alloc_q_vectors’ at drivers/net/ethernet/intel/i40e/i40e_main.c:12112:3:
  571 |         _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)
include/linux/rcupdate.h:1084:17: note: in expansion of macro ‘BUILD_BUG_ON’
 1084 |                 BUILD_BUG_ON(offsetof(typeof(*(ptr)), rhf) >= 4096);    \
drivers/net/ethernet/intel/i40e/i40e_main.c:5113:9: note: in expansion of macro ‘kfree_rcu’
 5113 |         kfree_rcu(q_vector, rcu);
      |         ^~~~~~~~~

The problem is that the 'rcu' member in 'q_vector' is too far from the start
of the structure. Move this member before the CPU mask instead, in all three
drivers.
