iput() ends up calling ->evict() on new inode, which is not yet initialized
by owning fs. So use destroy_inode() instead.
Add to sb->s_inodes list only after the inode has been inserted into the
hash. The exact point at which the inode is added onto the sb list
shouldn't matter as long as it is done while the inode is in the I_NEW
state.
