Check for null mBlastBufferQueue

Browse Source 
If there is a sync transaction, but blast is not enabled,
mNextDrawUseBLASTSyncTransaction will be true, but mBlastBufferQueue
will be null. This will cause a NPE when trying to call
mBlastBufferQueue.setNextTransaction

Test: Use sync transaction without blast
