Freeze when executing empty Batch query with PVD connected

[zemlifr]

When empty batch query is executed and pvd is connected, there is freeze because query collector is never unlocked.
Empty batch query is used by PxVehicleSuspensionRaycasts and similar functions when you skip all vehicles.

if PX_SUPPORT_PVD	
	PxU32 pvdRayQstartIdx = 0;
	PxU32 pvdOverlapQstartIdx = 0;
	PxU32 pvdSweepQstartIdx = 0;

	Vd::ScbScenePvdClient& pvdClient = mNpScene->mScene.getScenePvdClient();
	const bool needUpdatePvd = pvdClient.checkPvdDebugFlag() && (pvdClient.getScenePvdFlagsFast() & PxPvdSceneFlag::eTRANSMIT_SCENEQUERIES);

	if(needUpdatePvd)
	{
		mNpScene->getBatchedSqCollector().getLock().lock();
		isSqCollectorLocked = true;
	
		pvdRayQstartIdx = mNpScene->getBatchedSqCollector().mAccumulatedRaycastQueries.size();
		pvdOverlapQstartIdx = mNpScene->getBatchedSqCollector().mAccumulatedOverlapQueries.size();
		pvdSweepQstartIdx = mNpScene->getBatchedSqCollector().mAccumulatedSweepQueries.size();
	}
#endif

.........................

EARLY RETURN THERE, NO UNLOCK :(
	// data declarations for double buffering the input stream
	PxU32 curQueryOffset = 0; // first query starts at 0
	if (mPrevOffset == eTERMINAL) // except if zero queries were queued
	{
		finalizeExecute();
		return;
	}

	PxU32 hitsSpaceLeft; PX_UNUSED(hitsSpaceLeft);

	// ====================== parse and execute the batch query memory stream ====================== 
	PxU32 queryCount = 0;
	do {
.......................................
	} while (queryCount < 1000000);

#if PX_SUPPORT_PVD
	if( isSqCollectorLocked && needUpdatePvd)	
	{
		mNpScene->getBatchedSqCollector().collectAllBatchedHits( mDesc.queryMemory.userRaycastResultBuffer, mNbRaycasts, pvdRayQstartIdx, mDesc.queryMemory.userOverlapResultBuffer, mNbOverlaps, pvdOverlapQstartIdx,
 mDesc.queryMemory.userSweepResultBuffer, mNbSweeps, pvdSweepQstartIdx);
	}

	// Maybe connection is disconnected after the lock
	if( isSqCollectorLocked )
	{
		mNpScene->getBatchedSqCollector().getLock().unlock();
		isSqCollectorLocked = false;
	}
#endif

PVD section should be moved after early return
