Tanguy Pruvot 61ff92b5b4 never interrupt global benchmark with found nonces
fix some algo weird hashrates (like blake)
and reset device between algos, for better accuracy

but this reset doesnt seems enough to bench all algos correctly...

to test on linux, could be a driver issue...

heavy: fix first alloc and indent with tabs...
