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.
