Bug description:
  The test failed with file attribute not match,
  for "file", we're expecting:
  "--------c------- a/file", but lsattr shows:
  "--------c--------- a/file"

  for "file2", we're expecting:
  "---------------- a/file2", but lsattr shows:
  "------------------ a/file2"

  for "directory", we're expecting:
  "---------------- a", but lsattr shows:
  "------------------ a"

  
  This patch could be found in the Bionic tree.

  fix 78a017a2c92df9b571db0a55a016280f9019c65e

      Btrfs: add missing compression property remove in
  btrfs_ioctl_setflags

      The behaviour of a 'chattr -c' consists of getting the current flags,
      clearing the FS_COMPR_FL bit and then sending the result to the set
      flags ioctl - this means the bit FS_NOCOMP_FL isn't set in the flags
      passed to the ioctl. This results in the compression property not being
      cleared from the inode - it was cleared only if the bit FS_NOCOMP_FL
      was set in the received flags.

  Incorrect attributes on file, got: --------c--------- a/file
  Incorrect attributes on file2, got: ------------------ a/file2
  Incorrect attributes on directory, got: ------------------ a
