Zhenlei Huang 6000c9ebc2 ifnet: Defer detaching address family dependent data
While diagnosing PR 279653 and PR 285129, I observed that thread may
write to freed memory but the system does not crash. This hides the
real problem. A clear NULL pointer derefence is much better than writing
to freed memory.
