[SK_BUFF]: ipvs_property field must be copied

IPVS used flag NFC_IPVS_PROPERTY in nfcache but as now nfcache was removed the
new flag 'ipvs_property' still needs to be copied. This patch should be
included in 2.6.14.

Further comments from Harald Welte:

Sorry, seems like the bug was introduced by me.
