  Resolve a crash related to a T.38 reinvite race condition.
  
  This change resolves a crash observed locally during some T.38 testing.
  A call was set up using a call file, and when the T.38 reinvite came in,
  the channel state was still AST_STATE_DOWN.  The reason is explained by
  a comment in the code that previously lived in the handling of
  AST_STATE_RINGING.  This change modifies the logic to handle the same
  race condition for any channel state that is not UP.
  
  (closes ABE-1895)
