[PATCH 09/10] builtin/repack.c: extract loose object handling

[Taylor Blau <me@ttaylorr.com>]

'git repack -g' will have to learn about unreachable loose objects that
need to be removed in a separate path from the existing checks.

Extract that check into a function so it can be called from multiple
places.
