f2fs: align data types between on-disk and in-memory block addresses
The on-disk block address is defined as __le32, but in-memory block address, block_t, does as u64. Let's synchronize them to 32 bits. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>
