MFC 196589:
In the loop through the list of interfaces in network6_interface_setup()
rtsol_interface gets reset to "yes" each time through the loop, but
rtsol_available does not. If a user has lo0 first in their list of
interfaces rtsol_available will get set to "no" the first time through
the loop and subsequent interfaces will not get rtsol'ed when they should.
Therefore change the conditional for the is_wired() test to _interface.
