Function ice_tx_xsk_pool() used to get XSK buffer pool associated
with XDP Tx queue returns NULL when number of ordinary Tx queues
is not equal to num_possible_cpus().

The function computes XDP Tx queue ID as an expression
`ring->q_index - vsi->num_xdp_txq` but this is wrong because
XDP Tx queues are placed after ordinary ones so the correct
formula is `ring->q_index - vsi->alloc_txq`.

Prior commit 792b2086584f ("ice: fix vsi->txq_map sizing") number
of XDP Tx queues was equal to number of ordinary Tx queues so
the bug in mentioned function was hidden.

Reproducer:
host# ethtool -L ens7f0 combined 1
host# ./xdpsock -i ens7f0 -q 0 -t -N
samples/bpf/xdpsock_user.c:kick_tx:794: errno: 6/"No such device or address"

Thanks for this fix! I did exactly the same patch yesterday and it's
already applied to bpf tree:

I'm covering for Tony this week maintaining this tree.  He let me know there were a few patches you had to send Ivan and I was waiting on this one.  If I'm following correctly, this one will be dropped and the other ones are ready to be sent now to net then?

Yes, this one is beaten and the net tree already contains it[0].
There are still 3 Ivan's fixes not applied yet:
 * [1]
 * [2]
 * [3]

I'm wondering if it's worth to pass them through dev-queue since
they're urgent and have been tested already in 2 companies? They
could go directly to -net and make it into RC1.

Yes, this one is beaten and the net tree already contains it[0].
There are still 3 Ivan's fixes not applied yet:
 * [1]
 * [2]
 * [3]

I'm wondering if it's worth to pass them through dev-queue since
they're urgent and have been tested already in 2 companies? They
could go directly to -net and make it into RC1.

Yes, if you read my original message, I said to net =) I am the
one that takes it from here and sends to net.  I was asserting
that his changes were done now and ready to be sent to net or
if I was missing another patch he is working on before putting
it up.
