net: niu: fix format string overflow warning:
We get a warning for the port_name string that might be longer than
six characters if we had more than 10 ports:
drivers/net/ethernet/sun/niu.c: In function 'niu_put_parent':
drivers/net/ethernet/sun/niu.c:9563:21: error: '%d' directive writing between 1 and 3 bytes into a region of size 2 [-Werror=format-overflow=]
sprintf(port_name, "port%d", port);
^~~~~~~~
drivers/net/ethernet/sun/niu.c:9563:21: note: directive argument in the range [0, 255]
drivers/net/ethernet/sun/niu.c:9563:2: note: 'sprintf' output between 6 and 8 bytes into a destination of size 6
sprintf(port_name, "port%d", port);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/sun/niu.c: In function 'niu_pci_init_one':
drivers/net/ethernet/sun/niu.c:9538:22: error: '%d' directive writing between 1 and 3 bytes into a region of size 2 [-Werror=format-overflow=]
sprintf(port_name, "port%d", port);
^~~~~~~~
drivers/net/ethernet/sun/niu.c:9538:22: note: directive argument in the range [0, 255]
drivers/net/ethernet/sun/niu.c:9538:3: note: 'sprintf' output between 6 and 8 bytes into a destination of size 6
While we know that the port number is small, there is no harm in
making the format string two bytes longer to avoid the warning.
