qcacmn: Fix return type of auth type and akm

Currently api osif_nl_to_crypto_auth_type is trying to convert
the nl specific auth types to driver specific auth types but
it does not return the correct value, this api always returns
auth type as none as it never updates the return value after
the initialization.

While parsing WPA and WAPI, open authmode and cipher and akm are
set as none by default.

Thus return converted value of the auth type. Also fix the
return type of the akm conversion. Also avoid setting
open authmode and cipher and akm as none while parsing WPA
and WAPI ie.
