Subject: [PATCH] net/mlx5: fix UAR remapping on non configured queues
[ upstream commit fbab400f6143b8d41af7369309334cd22ac2751c ]
priv_tx_uar_remap() is wrongly considering the queue is already configured
and thus present in the queue array of the device.
Fixes: f8b9a3bad467 ("net/mlx5: install a socket to exchange a file descriptor")
