in: get rid of unused argument from ip_newid() and ip_newid_range()

in: take a reference of ifp on IP_ROUTETOIF
The ifp could be released after ia4_release(ia).

in: narrow the scope of ifa in ip_output (NFC)

sctp: follow the recent change of ip_newid()

in: avoid racy ifa_acquire(rt->rt_ifa) in ip_output()
If a rtentry is being destroyed asynchronously, ifa referenced by rt_ifa
can be destructed and taking ifa_acquire(rt->rt_ifa) aborts with a
KASSERT failure.  Fortunately, the ifa is not actually freed because of
a reference by rt_ifa, it can be available (except some functions like
psref) so as long the rtentry is held.

in: avoid racy ia4_acquire(ifatoia(rt->rt_ifa) in ip_rtaddr()
Same as the case of ip_output(), it's racy and should be avoided.
