i40e: fix registering XDP RxQ info

Browse source

[ Upstream commit 8f497dc8a6 ]

Current way of handling XDP RxQ info in i40e has a problem, where 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.
