c++: guard more against undiagnosed error_mark_node [PR112658]

This adds a sanity check to cp_parser_expression_statement similar to
the one in finish_expr_stmt added by r6-6795-g0fd9d4921f7ba2, which
effectively downgrades accepts-invalid/wrong-code bugs like this one
into ice-on-invalid/ice-on-valid ones.

PR c++/112658

gcc/cp/ChangeLog:

* parser.cc (cp_parser_expression_statement): If the statement
is error_mark_node, make sure we've seen_error().
