[PATCH u-boot 2/2] fs: btrfs: change directory list output to be aligned as before

[Marek Behún]

Since commit 325dd1f642dd ("fs: btrfs: Use btrfs_iter_dir() to ...")
when btrfs is listing a directory, the output is not aligned:

  <SYMLINK>         15  Wed Sep 09 13:20:03 2020  boot.scr -> @/boot/boot.scr
  <DIR>          0  Tue Feb 02 12:42:09 2021  @
  <FILE>        108  Tue Feb 02 12:54:04 2021  1.info

Return back to how it was displayed previously, i.e.:

  <SYM>         15  Wed Sep 09 13:20:03 2020  boot.scr -> @/boot/boot.scr
  <DIR>          0  Tue Feb 02 12:42:09 2021  @
  <   >        108  Tue Feb 02 12:54:04 2021  1.info

Instead of '<FILE>', print '<   >', as ext4 driver.

If an unknown directory item type is encountered, we will print the type
number left padded with spaces, enclosed by '?', instead of '<' and '>',
i.e.:

  ? 30?        .............................  name
