Problem: we don't evaluate given expression checking values of the slow_query_log_file/general_log_file, don't check it for NULL. Fix: evaluate the expression, check result returned. mysql-test/r/log_state.result: Fix bug #31604: server crash when setting slow_query_log_file/global general_log_file variable - test result. mysql-test/t/log_state.test: Fix bug #31604: server crash when setting slow_query_log_file/global general_log_file variable - test case. sql/set_var.cc: Fix bug #31604: server crash when setting slow_query_log_file/global general_log_file variable - evaluate var->value calling val_str() method; - check for null values returned; - return proper errors if any.
