Subject: [PATCH] net/mlx4_core: Protect QUERY_PORT wrapper from untrusted
 guests

The function mlx4_QUERY_PORT_wrapper implements only the
QUERY_PORT "general" case (opcode modifier = 0).

Verify that the opcode modifier is zero, and also that the
input modifier contains only the port number in bits 0..7
(all other bits should be zero).
