[PATCH 09/12] server-info: drop nr_alloc struct member

[Jeff King <peff@peff.net>]

We keep an array of struct pointers, with each one representing a single
packfile. But for some reason there is a nr_alloc parameter inside each
struct, which has never been used.

This is probably cruft left over from development, where we might have
wanted a nr_alloc to dynamically grow the list. But as it turns out, we
do not dynamically grow the list at all, but rather count up the total
number of packs and use that as a maximum size. So while we're thinking
of this, let's add an assert() that documents (and checks!) that our
allocation and fill loops stay in sync.
