net/mac80211: move WEP handling to ARC4 library interface
The WEP code in the mac80211 subsystem currently uses the crypto API to access the arc4 (RC4) cipher, which is overly complicated, and doesn't really have an upside in this particular case, since ciphers are always synchronous and therefore always implemented in software. Given that we have no accelerated software implementations either, it is much more straightforward to invoke a generic library interface directly.
