[PATCH] builtin/send-pack: report gpg config errors

[Stefan Beller <sbeller@google.com>]

Any caller except of git_gpg_config() except the one in send_pack_config()
handles the return value of git_gpg_config(). Also handle the return value
there.

There was no need for other configuration to be loaded and signing
pushes is the first that needs repository configuration.

Looking at 68c757f2199 (push: add a config option push.gpgSign for default
signed pushes, 2015-08-19) further, maybe we want to also have this?

Thanks,
Stefan
