extra_subflows is a u8 counter that can underflow if a decrement races with or precedes an increment. While the recently fixed userspace PM subflow creation path eliminated the primary cause, add defensive WARN_ON_ONCE guards at both decrement sites to catch any remaining edge cases rather than silently wrapping to 255.
