Since we are calculating a free space fragmentation, we should weight metaslabs by the amount of their free space, not a full size. Fragmentation of full metaslabs may not matter in presence empty ones. The old algorithm did not differentiate metaslabs having only one free 4KB block from metaslabs having 50% of space free in 4KB blocks, reporting higher fragmentation. While there, move metaslab_group_alloc_update() call after setting mg_fragmentation, otherwise the effect may be delayed by one TXG.
