Fix arena data structure size calculation.

Browse source 
Fix paren placement so that QUANTUM_CEILING() applies to the correct
portion of the expression that computes how much memory to base_alloc().
In practice this bug had no impact.  This was caused by
5d8db15db9 (Simplify run quantization.),
which in turn fixed an over-allocation regression caused by
3c4d92e82a (Add per size class huge
allocation statistics.).
