fix: silence unused withLock result warning in OutlineImageProvider

lock.withLock { inFlight.remove(url) } inside the defer returned
Set.remove's String? result unused - withLock mirrors its closure's
return type, so an unused Set.remove leaked through as an unused
withLock result. Explicitly discard it inside the closure instead.
