The test_dummy_encryption mount option isn't supposed to be settable or
changeable via a remount, so add test cases for this.  This is a
regression test for a bug that was introduced in Linux v5.17 and fixed
in v5.19-rc3 by commit 85456054e10b ("ext4: fix up test_dummy_encryption
handling for new mount API").
