Title
ice: fix crash in ethtool offline loopback test
Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: fix crash in ethtool offline loopback test
Since the conversion of ice to page pool, the ethtool loopback test
crashes:
BUG: kernel NULL pointer dereference, address: 000000000000000c
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page

It crashes because we have not initialized libeth for the rx ring.
Fix it by treating ICE_VSI_LB VSIs slightly more like normal PF VSIs and
letting them have a q_vector. It's just a dummy, because the loopback
test does not use interrupts, but it contains a napi struct that can be
passed to libeth_rx_fq_create() called from ice_vsi_cfg_rxq() ->
ice_rxq_pp_create().
