The first call will always pass the `p->size == p->length` check b/c both values are 0. Then GUEST_EXEC_IO_SIZE bytes will be allocated for the stream. But when we reap the exited process there's a `gei->err.length > 0` check to actually free the buffer. Which does not get run if the command doesn't write to the stream. Fix by making free() unconditional.
