Alexander Motin 6ff89fe126 Improve sorted scan memory accounting
Since we use two B-trees q_exts_by_size and q_exts_by_addr, we should
count 2x sizeof (range_seg_gap_t) per node.  And since average B-tree
memory efficiency is about 75%, we should increase it to 3x.

Previous code under-counted up to 30% of the memory usage.
