[PATCH net 1/4] net/mlx5: fs, Fix inverted cap check in tx flow table root disconnect

[Tariq Toukan]

From: Shay Drory <shayd@xxxxxxxxxx>

The capability check for reset_root_to_default was inverted, causing
the function to return -EOPNOTSUPP when the capability IS supported,
rather than when it is NOT supported.

Fix the capability check condition.

Fixes: 3c9c34c32bc6 ("net/mlx5: fs, Command to control TX flow table root")
