route(8) fix

[Bjoern A. Zeeb]

Hi,

can someone please review the below patch and see if it’s correct?
I did a simple 1:1 replacement without thinking about the code.

! When switching variables to flags in r243185 a few cases were missed.
! After r263152 this leaves unused variables if route(8) is compiled
! without INET support.
