staging: vt6656: Fix pairwise key entry save.
commit 0b59f10b1d8fe8d50944f21f5d403df9303095a8 upstream. The problem is that the group key was saved as VNT_KEY_DEFAULTKEY was over written by the VNT_KEY_GROUP_ADDRESS index. mac80211 could not clear the mac_addr in the default key. The VNT_KEY_DEFAULTKEY is not necesscary so remove it and set as VNT_KEY_GROUP_ADDRESS. mac80211 can clear any key using vnt_mac_disable_keyentry.
