ice: stop storing XDP verdict within ice_rx_buf

Browse source

[ Upstream commit 468a1952df ]

Idea behind having ice_rx_buf::act was to simplify and speed up the Rx
data path by walking through buffers that were representing cleaned HW
Rx descriptors. Since it caused us a major headache recently and we
rolled back to old approach that 'puts' Rx buffers right after running
XDP prog/creating skb, this is useless now and should be removed.

Get rid of ice_rx_buf::act and related logic. We still need to take care
of a corner case where XDP program releases a particular fragment.

Make ice_run_xdp() to return its result and use it within
ice_put_rx_mbuf().
