Subject: [PATCH 7/8] keyfile: cleanup error argument for read_field()
Rename @error to @out_err_str, because @error is usually used for GError
output arguments.
Also, make the string variables "const char *".
Use nm_assert() in read_field(), because it is a static function
with only four call sites. It's easily verified that the assertion
holds, so no need for a run-time check in production builds.
