Log Message:
Avoid double rt_replace_ifa on rtrequest1(RTM_ADD)

Some callers of rtrequest1(RTM_ADD) adjust rt_ifa of an rtentry created by
rtrequest1 that may change rt_ifa (in ifa_rtrequest) with another ifa that is
different from requested one.  It's wasteful and even worse introduces a race
condition.  rtrequest1 should just use a passed ifa as is if a caller hopes so.
