Subject: [PATCH 2/3] erofs: remove obsoluted comments

Some comments haven't been useful anymore since the code updated.
Let's drop them instead.

- * Logical to physical block mapping

- * Different with other file systems, it is used for 2 access modes:
- *
- * 1) RAW access mode:
- *
- * Users pass a valid (m_lblk, m_lofs -- usually 0) pair,
- * and get the valid m_pblk, m_pofs and the longest m_len(in bytes).
- *
- * Note that m_lblk in the RAW access mode refers to the number of
- * the compressed ondisk block rather than the uncompressed
- * in-memory block for the compressed file.
- *
- * m_pofs equals to m_lofs except for the inline data page.
- *
- * 2) Normal access mode:
- *
- * If the inode is not compressed, it has no difference with
- * the RAW access mode. However, if the inode is compressed,
- * users should pass a valid (m_lblk, m_lofs) pair, and get
- * the needed m_pblk, m_pofs, m_len to get the compressed data
- * and the updated m_lblk, m_lofs which indicates the start
- * of the corresponding uncompressed data in the file.
