[PATCH 3/7] Ensure packed_git.next is initialized to NULL.

["Shawn O. Pearce" <spearce@spearce.org>]

Junio noticed while reviewing this patch series that I removed the
initialization of packed_git.next = NULL in 88078baa.  That removal
was not intended so I'm restoring the initialization where necessary.
