Recovery of icreate transactions assumes hardcoded values for the inode
count and chunk length.
Sparse inode chunks are allocated in units of the cluster size. Update
the icreate validity checks to allow for appropriately sized inode
chunks and verify the inode count matches what is expected based on the
extent length rather than assuming a hardcoded count.
