Xiang hit an assertion failure during testing that is basically due to a
Nevada bug where some codepaths call ipif_arp_down() even on a
non-ILLF_XRESOLV IPv6 interface. However, I think the right fix is to
rename ipif_arp_down() to ipif_resolver_down() and have it work like
ipif_resolver_up(), in the sense that it will simply return if it's called
on an IPv6 interface that's not ILLF_RESOLV. This simplifies the code a
bit and resolved the bug. Seb, can you take a look?
