Robert Griesemer c801e4b10f cmd/compile/internal/syntax: use BadExpr instead of fake CallExpr in bad go/defer
If the go/defer syntax is bad, using a fake CallExpr may produce
a follow-on error in the type checker. Instead store a BadExpr
in the syntax tree (since an error has already been reported).

Adjust various tests.

For #54511.
