mwifiex: return success in set_default_key for WPA/WPA2
When testing wpa_supplicant with 'nl80211' driver to connect
to an AP with WPA/WPA2 security, we notice the followings:
1) add_key is called firstly with the key from cfg80211
2) set_defaut_key is called next
set_default_key() is specific to WEP keys and should not be
called in case of WPA/WPA2 security. The set_default_key()
won't be called if wpa_supplicant uses "-Dwext" option,
but it's been called if "-Dnl80211" option is specified.
We can fix this issue by adding a check to return from
set_default_key() if WEP key is not configured.
