The default value of 8 is too small to read /sys/class/infiniband/usnic_x/node_type, which contains "6: usNIC UDP". Per a7a73a8c1b39362f1701256bc772d82847832f9c, the too-small buffer causes a stderr warning to be emitted from ibv_devinfo when reading usNIC devices.
This commit therefore increases the buffer size to 16, which is long enough to read the usNIC node_type value.
