Remove a wrong assertion in ifaref

 -

Doing ifref on an ifa with IFA_DESTROYING is not a problem; the reference should
be dropped during the destruction of the ifa.

 -

Use atomic operations for ifa_refcnt

 -

Avoid a dangling pointer during rt_replace_ifa

 -

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.

 -

Use rt_update framework on updating a rtentry
