e2fsck: ea_inode hash validation
In original implementation of ea_inode feature, each xattr inode had
a single parent. Child inode tracked the parent by storing its inode
number in i_mtime field. Also, child's i_generation matched parent's
i_generation.
With deduplication support, xattr inodes can now be shared so a single
backpointer is not sufficient to achieve strong binding. This is now
replaced by hash validation.
