Bug report: 'filtering content' delayed progress message does not respect --quiet

[Sean Allred <allred.sean@gmail.com>]

Hi folks,

Submitting the filled-out template from git-bugreport. Let me know if
I can be of any assistance.

Thanks!

Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)

  Called `git clone --quiet git://path/to/private/repo`

What did you expect to happen? (Expected behavior)

  Expected git to be quiet :-)  Did not expect writes to stderr/stdout.

What happened instead? (Actual behavior)

  Received output that looked like

      Filtering content:  --% (--/--), --.-- MiB | --.-- MiB/s

What's different between what you expected and what actually happened?

  `--quiet` should suppress all output, but in actuality, that line
  was still output.

Anything else you want to add:

  Submitting from https://github.com/git-lfs/git-lfs/issues/1270 (re
  https://github.com/git-lfs/git-lfs/issues/1270#issuecomment-461176647).
  Other details may be available there.

  I've verified I can still reproduce on the current version of git
  (listed below) with a private repo (note to self:
  gid://gitlab/Project/2458).

  It looks like we need similar handling from
  index_pack.c:resolve_deltas at entry.c:finish_delayed_checkout.  It
  looks like the necessary state may not be available where it's
  needed, but this is based on about two minutes of reading :-)

Please review the rest of the bug report below.
