[BUG] Cloning with git HEAD fails for some repositories

Initial cloning via

    git clone http://git.denx.de/u-boot-efi.git

fails with git version 2.21.0.196.g041f5ea1cf

git version 2.1.4 works fine.

Bisection points to this first bad commit: 17966c0a63d25b1cc2dd1e98d30873e643bd581f http: avoid disconnecting on 404s for loose objects

Please, fix the regression.

Setting

    git config --global \
    http.http://git.denx.de/u-boot-efi.git.followRedirects true

avoids the warning but does not solve the problem:

$ git clone http://git.denx.de/u-boot-efi.git Cloning into 'u-boot-efi'... warning: adding alternate object store: http://git.denx.de/u-boot.git/ error: Unable to find a00d15757d7a513e410f15f2f910cb52333361a3 under http://git.denx.de/u-boot-efi.git Cannot obtain needed object a00d15757d7a513e410f15f2f910cb52333361a3 error: fetch failed.
