net: Fix Tx hash bound checking
Fixes the lower and upper bounds when there are multiple TCs and
traffic is on the the same TC on the same device.
The lower bound is represented by 'qoffset' and the upper limit for
hash value is 'qcount + qoffset'. This gives a clean Rx to Tx queue
mapping when there are multiple TCs, as the queue indices for upper TCs
will be offset by 'qoffset'.
v2: Fixed commit description based on comments.
Fixes: 1b837d489e06 ("net: Revoke export for __skb_tx_hash, update it to just be static skb_tx_hash")
Fixes: eadec877ce9c ("net: Add support for subordinate traffic classes to netdev_pick_tx")
