patch 9.1.1852: vim9class: memory leak in parse_member()
Problem: vim9class: fix memory leak in parse_member()
Solution: Free evalarg before returning (Lidong Yan)
In parse_member(), skip_expr_concatenate() allocates memory in evalarg.
However parse_member() forgets to free evalarg at early return-fail
point. Add clear_evalarg() at early return-fail point.
closes: #18533
