parse.c: Wrap FREE_CIDX definition in do { ... } while(0)

Makes it match the definition in create.c and eliminates
clang warnings:

create.c:2409:13: warning: empty expression statement has no effect;
 remove unnecessary ';' to silence this warning [-Wextra-semi-stmt]
                        FREE_CIDX;
                                 ^
create.c:2440:17: warning: empty expression statement has no effect;

                            FREE_CIDX;
                                     ^
