staging/rtl8192e: Register against lib80211

Browse Source 
Convert rtllib from registering the crypt drivers against rtllib_crypt
and instead register the against lib80211. The crypto functions have
R- prepended (R-CCMP, R-TKIP, R-WEP) so they will not clash with the
lib80211 versions.

We cannot use the lib80211 crypt drivers since the rtl8192e has some
hardware support that is not handled by the lib80211 crypt drivers.
