Vulkan: Fix barrier batching past limit (#6339)

If more than 16 barriers were queued at one time, the _queuedBarrierCount would no longer match the number of remaining barriers, because when breaking out of the loop consuming them it deleted all barriers, not just the 16 that were consumed.

Should fix freezes that started occurring with #6240. Fixes issue #6338.
