force the decryption

with some 802.11 drivers the WEP payload is already decrypted. It was the case
for  Centrino in Promisc  mode.
It also seem to be the case for the Madwifi-ng driver .... then I add an option
in the IEEE802.11 Preferences to force the decryption in these cases.
This option assumes that packets that fails WEP decryption (because No key is
present or only bad keys) are already decrypted.
Then it keeps the WEP Parameters and dissect the unencrypted data. Packets that
succeeds in Wep decryption still remain correctly dissected.
