Harshavardhana 05e53f1b34 api: CopyObjectPart was copying wrong offsets due to shadowing. (#3838)
startOffset was re-assigned to '0' so it would end up
copying wrong content ignoring the requested startOffset.

This also fixes the corruption issue we observed while
using docker registry.

Fixes https://github.com/docker/distribution/issues/2205

Also fixes #3842 - incorrect routing.
