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]
