Partial clone fails with file:/// URI

Hi friends,

When I run a git clone with --filter and a file:/// URI - it fails.

Repro steps:

I have the `git` repo cloned and built into the CWD at v2.28.0 git/git clone --filter=blob:none file:///home/nipunn/src/git git2

nipunn@nipunn-dbx:~/src$ git/git clone --filter=blob:none file:///home/nipunn/src/git git2 Cloning into 'git2'... warning: templates not found in /home/nipunn/share/git-core/templates remote: Enumerating objects: 177110, done. remote: Counting objects: 100% (177110/177110), done. remote: Compressing objects: 100% (61436/61436), done. Receiving objects: 100% (177110/177110), 62.58 MiB | 43.95 MiB/s, done. remote: Total 177110 (delta 114305), reused 176904 (delta 114102), pack-reused 0 Resolving deltas: 100% (114305/114305), done. fatal: the remote end hung up unexpectedly fatal: protocol error: bad pack header warning: Clone succeeded, but checkout failed. You can inspect what was checked out with 'git status' and retry with 'git restore --source=HEAD :/'

It seems to work ok with a remote URI or w/o a --filter arg. I was able to confirm that the "bad pack header" is a "-1" response code PH_ERROR_EOF Perhaps the `fatal: protocol error: bad pack header` - should include the error code as well. Thanks --Nipunn
