[PATCH net-next] octeontx2-af: nix: Log TX scheduler queue validation failures

[Ratheesh Kannoth <rkannoth@marvell.com>]

From: Subbaraya Sundeep <sbhatta@marvell.com>

Emit dev_err() when is_valid_txschq() rejects a scheduler queue
mapping so misconfigured TX scheduler allocations are easier to
diagnose.
