Fix HS20_GET_NAI_HOME_REALM_LIST hex length check (CID 68108)

Browse Source 
Due to an incorrect operation (MOD vs. AND), the code that was supposed
to return an error if the hex string has odd length was not really
reporting any failures. Instead of reporting an error, the invalid
control interface command would have been truncated. This is not an
issue in practice, but better fix the implementation anyway.
