Fix arithmetic in init/max mem ratio correction

Browse Source 
Qubes Manager seems to try to guarantee that 10*init_mem is at
least max_mem by automatically adjusting init_mem to max_mem/10 if
inappropriate values are set. However, this may not guarantee that
10*init_mem >= max_mem due to rounding errors. This change fixes
these edge cases by basically rounding up the result of division
by 10.
