f2fs: iostat: support accounting compressed IO

Browse Source 
Previously, we supported to account FS_CDATA_READ_IO type IO only,
in this patch, it adds to account more type IO for compressed file:
- APP_BUFFERED_CDATA_IO
- APP_MAPPED_CDATA_IO
- FS_CDATA_IO
- APP_BUFFERED_CDATA_READ_IO
- APP_MAPPED_CDATA_READ_IO
