Peter Hutterer c8c1c07a2a tools: fix swapped fread arguments causing DMI modalias to always be "unknown" 
fread(buf, sizeof(buf), 1, dmi) reads one block of 2048 bytes,
returning the number of complete blocks (0 or 1). Since DMI modalias
files are always shorter than 2048 bytes, fread returns 0 even when
data was successfully read into buf. The 'if (n > 0)' check then
always fails and the DMI string stays as "unknown".

Swap the size and nmemb arguments so fread returns the number of
bytes read instead.

Fixes: 0ecd08c134 ("tools: use __attribute__(cleanup)")
