That makes log confusing. Update the error path to print log only when the caller attempts to free nonzero-size buffer with VA being NULL, which indicates something indeed went wrong. This brings another benefit that the callers no more need to check mem->va explicitly to avoid the error, which can make the code more compact and neat.
