revlog: fix wrong type of rank_unknown variable

We treat "rank" as an int everywhere, but declare rank_unknown as a
char.  On architectures where char is signed, that works out ok, but
when char is unsigned, rank_unknown is 255 instead of -1.

  $ hg ci -m first
  $ echo a > to-be-deleted
  $ hg ci -m second
  $ rm to-be-deleted
  $ hg diff -r 0

Same issue, different code path
