The icreate log item is currently hardcoded to an inode count of 64 inodes. The agbno and extent length are used to initialize the inode chunk from log recovery. While an incorrect inode count does not lead to bad inode chunk initialization, we should pass the correct inode count such that log recovery has enough data to perform meaningful validity checks on the chunk.
