segfault in sensord (lm_sensors2 2.8.5)

[Tim Toohey]

Hi,

In prog/sensord/rrd.c (since revision 1.5 I think) there's a null pointer 
dereference when used with the --load-average option. This seems to only be a 
problem when initialing creating the rrd log file (though I'm not sure).

Below is my fix.

Thanks,
Tim Toohey
