net/mlx5e: Do not ignore netdevice TX/RX queues number
The current design of mlx5e driver ignores the netdevice TX/RX queues
number for netdevices that RDMA IPoIB ULP creates. Instead, the queue
number is initialized to the maximum number that mlx5 thinks best for
performance. As a result, ULP drivers that choose to create a netdevice
with queue number that is less than the maximum channels mlx5 creates,
will get a memory corruption.
This fix changes the mlx5e netdev logic to respect ULP netdevices TX/RX
queue number and use it when creating resources instead of the maximum
channel number.
Fixes: cd565b4b51e5 ("IB/IPoIB: Support acceleration options callbacks")
