ext4: optimize Hurd tests when reading/writing inodes
Set a in-memory superblock flag to indicate whether the file system is
designed to support the Hurd.
Also, add a sanity check to make sure the 64-bit feature is not set
for Hurd file systems, since i_file_acl_high conflicts with a
Hurd-specific field.
