Remove station functionality from hostap and madwifi driver wrappers

Browse source 
This has been obsoleted by the more generic Linux WEXT (driver_wext.c)
support. The hostap and madwifi driver wrappers can now be used only
with hostapd. The old station interface remains available in releases up
to 1.x.
