erofs-utils: lib: read i_ino in erofs_read_inode_from_disk()
i_ino[0] is a unique inode serial number in the erofs filesystem to
count inodes one by one, while i_ino[1] is a unique number identifying
the source inode in the source directory, which is usually derived from
st->st_ino.
Read on-disk ino and store it in i_ino[0] given the above background.
Fixes: 5e35b75ad499 ("erofs-utils: introduce fuse implementation")
