Fix #202: Infinite loop in sadf

Check that structure's size is greater than 0 even for
unknown activities.
Else trying to skip this unknown activity in read_file_stat_bunch()
function will decrease offset pointer in file and result in an
infinite loop:

offset = (off_t) fal->size * (off_t) nr_value * (off_t) fal->nr2;
