mem-pool: simplify alignment calculation
Use DIV_ROUND_UP in mem_pool_alloc() to round the allocation length to the next multiple of GIT_MAX_ALIGNMENT instead of twiddling bits explicitly. This is shorter and clearer, to the point that we no longer need the comment that explains what's being calculated.
