Gao Xiang 15f7b18691 erofs: fix extended inode could cross boundary ... commit 0dcd3c94e0 upstream. Each ondisk inode should be aligned with inode slot boundary (32-byte alignment) because of nid calculation formula, so all compact inodes (32 byte) cannot across page boundary. However, extended inode is now 64-byte form, which can across page boundary in principle if the location is specified on purpose, although it's hard to be generated by mkfs due to the allocation policy and rarely used by Android use case now mainly for > 4GiB files. For now, only two fields `i_ctime_nsec` and `i_nlink' couldn't be read from disk properly and cause out-of-bound memory read with random value. Let's fix now.
