Do not clear RSN parameters before full configuration

This fixes an issue where hostapd SET command is used to configure RSN
parameters and the wpa parameter is sent after the other parameters.
Previously, the default case here ended up clearing rsn_pairwise and
wpa_pairwise values and once wpa=2 was finally set, the cipher
configuration had already been lost.
