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]
