Previous code allowed each metaslab group to have different number of allocators. But in practice it worked only for embedded SLOGs, relying on a number of conditions and creating a significant mine field if any of those change. I just stepped on one myself. This change makes all groups to have spa_alloc_count allocators. It may cost us extra 192 bytes of memory per normal top-level vdev on large systems, but I find it a small price for cleaner and more reliable code.
