MDEV-11060 sql/protocol.cc:532: void Protocol::end_statement(): Assertion `0' failed

Browse Source 
In file sql/opt_range.cc,when calculate_cond_selectivity_for_table() is called with optimizer_use_condition_selectivity=4 then
	- thd->no_errors is set to 1
	- the original value of thd->no_error is not restored to its original value
	- this is causing the assertion to fail in the subsequent queries

Fixed by restoring the original value of thd->no_errors
