hlr.c: replace deprecated osmo_gsup_get_err_msg_type()

Use OSMO_GSUP_TO_MSGT_ERROR() instead. The other function has been
deprecated in [1].

Remove the < 0 return check, because the macro doesn't do any error
handling. It relies on all "request" messages having an appropriate
"error" message, which is part of the GSUP spec now (see [2]).
