[PATCH 03/13] erofs-utils: lib: read i_ino in erofs_read_inode_from_disk()

[Jingbo Xu <jefflexu@linux.alibaba.com>]

i_ino[0] is a unique inode serial number in the erofs filesystem where
the inode resides, and also serves as the on-disk inode number, 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.
