ext4: fix an endianness bug in ext4_encrypted_zeroout()
commit e2c9e0b28e146c9a3bce21408f3c02e24ac7ac31 upstream.
ex->ee_block is not host-endian (note that accesses of other fields
of *ex right next to that line go through the helpers that do proper
conversion from little-endian to host-endian; it might make sense
to add similar for ->ee_block to avoid reintroducing that kind of
bugs...)
