For requests on paths like admin/metadata/bucket/foobar which'll try to initialize quota fail as s->bucket or s->bucket_name aren't populated, which crashes on dereferencing bucket related params. Normal S3/Swift protocol requests would've populated s->bucket in post_auth_init or while parsing policies.
