Subject: [net-next 14/14] net/mlx5: Don't query MAX caps twice

From: Shay Drory <shayd@...dia.com>

Whenever mlx5 driver is probed or reloaded, it queries some capabilities
in MAX mode via set_hca_cap() API. Afterwards, the driver queries all
capabilities in MAX mode via mlx5_query_hca_caps() API.

Since MAX caps are read only caps, querying them twice is redundant.
Hence, delete the second query.
