ipv6: keep existing flags when setting IFA_F_OPTIMISTIC
[ Upstream commit 9a1ec4612c9bfc94d4185e3459055a37a685e575 ]
Commit 64236f3f3d74 ("ipv6: introduce IFA_F_STABLE_PRIVACY flag")
failed to update the setting of the IFA_F_OPTIMISTIC flag, causing
the IFA_F_STABLE_PRIVACY flag to be lost if IFA_F_OPTIMISTIC is set.
