Log:
  m_getm2: correct a comment.
  
  The comment states that function always return a top of allocated mbuf;
  however, the function actually return the overall mbuf chain top pointer.
  
  Since there are already existing users of it (via m_getm(4) macro),
  rephrase the comment and leave behavior unchanged.
