Subject: [PATCH bpf v3 5/9] i40e: fix registering XDP RxQ info

Current way of handling XDP RxQ info in i40e has following problems:
* when xsk_buff_pool is detached, memory model is not unregistered
before
  registering a new one, this leads to a dangling xsk_buff_pool in the
  memory model table
* frag_size is not updated when xsk_buff_pool is detached or when MTU
is
  changed, this leads to growing tail always failing for multi-buffer
  packets.

Couple XDP RxQ info registering with buffer allocations and
unregistering with cleaning the ring.

Fixes: a045d2f2d03d ("i40e: set xdp_rxq_info::frag_size")
