Subject: [PATCH] Xi: don't memcpy the KeyClassRec from SD to MD. #16167

Most of its component get copied during CopyKeyClass anyway.
The ones that aren't:
  postdown - never changed for virtual devices anyway.
  down - shouldn't change that without sending events.

memcpy'ing the struct also copied mapWidth, which means we didn't realloc
during SetKeySymsMap lateron, overwriting the memory assigned to us.
