Commit d0e8c47c58575b9131e786edb488fd029eba443e added support for extended ids
but seems to break on flashes which don't have an extended id defined.  If the
table does not have an extid defined, then we should ignore it.

Quoting a bare hash in the changelog is a bit reader-hostile and I
believe there's some git-related issue which can cause people to not be
able to find the commit at all (I'm not sure what the circumstances
are, but Linus has mentioned it a couple of times when asking people to
not quote bare commit IDs in changelogs).

So when referencing a previous commit please use this form:

   Commit d0e8c47c58575b9131e786edb488fd029eba443e ("m25p80.c
   extended jedec support").
