GSUP: deprecate osmo_gsup_get_err_msg_type()
Replace osmo_gsup_get_err_msg_type() with a wrapper to OSMO_GSUP_TO_MSGT_ERROR(). This macro assumes, that all error messages are (request message | 0x000001). Add a big comment header for osmo_gsup_message_type, describing this already implicitly followed rule and therefore making it explicit. With this change, we don't need to maintain the request -> error message mapping in osmo_gsup_get_err_msg_type() anymore.
