net: ethernet: ti: am65-cpsw: Fix NULL dereference on XDP_TX
If number of TX queues are set to 1 we get a NULL pointer
dereference during XDP_TX.
~# ethtool -L eth0 tx 1
~# ./xdp-trafficgen udp -A <ipv6-src> -a <ipv6-dst> eth0 -t 2
Transmitting on eth0 (ifindex 2)
[ 241.135257] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000030
Fix this by using actual TX queues instead of max TX queues
when picking the TX channel in am65_cpsw_ndo_xdp_xmit().
Fixes: 8acacc40f733 ("net: ethernet: ti: am65-cpsw: Add minimal XDP support")
