[PATCH net-next 2/7] net/mlx4_core: Use correct variable type for mlx4_slave_cap

[Or Gerlitz <ogerlitz@mellanox.com>]

From: Matan Barak <matanb@mellanox.com>

We've used an incorrect type for the loop counter and the
mlx4_QUERY_FUNC_CAP function. The current input modifier
is either a port or a boolean.
Since the number of ports is always a positive value < 255,
we should use u8 instead of an integer with casting.
