ext4: start handle at the last possible moment when creating inodes
In ext4_{create,mknod,mkdir,symlink}(), don't start the journal handle until the inode has been succesfully allocated. In order to do this, we need to start the handle in the ext4_new_inode(). So create a new variant of this function, ext4_new_inode_start_handle(), so the handle can be created at the last possible minute, before we need to modify the inode allocation bitmap block.
