erofs: ensure m_llen is reset to 0 if metadata is invalid
Sometimes, the on-disk metadata might be invalid due to user
interrupts, storage failures, or other unknown causes.
In that case, z_erofs_map_blocks_iter() may still return a valid
m_llen while other fields remain invalid (e.g., m_plen can be 0).
Due to the return value of z_erofs_scan_folio() in some path will
be ignored on purpose, the following z_erofs_scan_folio() could
then use the invalid value by accident.
Let's reset m_llen to 0 to prevent this.
