  Log:
  MFC 1.113:
    Several fixes to rt_setgate(), that fix problems with route changing:
  
    - Rearrange code so that in a case of failure the affected
      route is not changed. Otherwise, a bogus rtentry will be
      left and later rt_check() can recurse on its lock. [1]
    - Remove comment about protocol cloning.
    - Fix two places where rtentry mutex was recursed on, because
      accessed via two different pointers, that were actually pointing
      to the same rtentry in some cases. [1]
    - Return EADDRINUSE instead of bogus EDQUOT, in case when gateway
      uses the same route. [2]
