Current compr_blocks of superblock info is not 64bit value. We are
accumulating each i_compr_blocks count of inodes to this value and
those are 64bit values. So, need to change this to 64bit value.
It's not a big deal, as f2fs use 32bits to index block device's address space,
so there is at most 1 << 32 blocks in f2fs, we can not save more blocks than
the number...
If it overflows 32bits variable's space, it must be a bug.
