[IPV6]: Fix source address selection.

The commit 95c385 broke proper source address selection for cases in which
there is a address which is makred 'deprecated'. The commit mistakenly
changed ifa->flags to ifa_result->flags (probably copy/paste error from a
few lines above) in the 'Rule 3' address selection code.

The patch restores the previous RFC-compliant behavior.
