Merge branch 'md/list-lazy-objects-fix'

Browse Source 
"git rev-list --exclude-promisor-objects" had to take an object
that does not exist locally (and is lazily available) from the
command line without barfing, but the code dereferenced NULL.

* md/list-lazy-objects-fix:
  list-objects.c: don't segfault for missing cmdline objects
