format-patch: use 'origin' as start of current-series-range when known
When formatting a patch series over `origin..HEAD`, one would expect
that range to be used as the current-series-range when computing a
range-diff between the previous and current versions of a patch series.
However, infer_range_diff_ranges() ignores `origin..HEAD` when
--range-diff=<prev> specifies a single revision rather than a range, and
instead unexpectedly computes the current-series-range based upon
<prev>. Address this anomaly by unconditionally using `origin..HEAD` as
the current-series-range regardless of <prev> as long as `origin` is
known, and only fall back to basing current-series-range on <prev> when
`origin` is not known.
