net/mlx4_core: Fix init_port mask state for slaves
In function mlx4_INIT_PORT_wrapper, the port state mask for the slave is only set if we are invoking the INIT_PORT fw command. However, the reference count for the (initialized) port is incremented anyway. This creates a problem in that when we have multiple slaves, then the CLOSE_PORT command will never be invoked. The reason is that in the CLOSE_PORT wrapper, if the port-state mask is zero for the slave (which it is), the wrapper returns without doing anything. The only slave which will not return immediately in the CLOSE_PORT wrapper is that slave for which INIT_PORT was invoked. The fix is to not have the port-state mask setting depend on the logic for calling the INIT_PORT fw command.
