UploadPack: Clear advertised ref map after negotiation
After negotiation phase of a fetch, the advertised ref map is no longer used and
can be safely cleared. For >1GiB repos object selection and packfile writing may
take 10s of minutes. For the chromium.googlesource.com/chromium/src repo, this
advertised ref map is >400MiB. Returning this memory to the Java heap is a major
scalability win.
