Delete MacCall case from pretty-printing semicolon after StmtKind::Expr

Browse Source 
I didn't figure out how to reach this condition with `expr` containing
`ExprKind::MacCall`. All the approaches I tried ended up with the macro
call ending up in the `StmtKind::MacCall` case below instead.

In any case, from visual inspection this is a bugfix. If we do end up
with a `StmtKind::Expr` containing `ExprKind::MacCall` with brace
delimiter, it would not need ";" printed after it.
