[#MDEV-32844] THD::rli_fake/rgi_fake not cleared on new connection

# The bug was that the THD::rli_fake was not cleared when the THD is re-used

# for the new connection, and we would get a warning from the following

# statement.

SET SESSION pseudo_slave_mode= 1;

--disconnect con1

This has occasionally been observed as random failure of test case sys_vars.character_set_results_basic, depending on what tests ran before it.
