iris: Order CS stall and TC invalidate for format reinterpretation hacks

Browse Source 
This should ensure the TC invalidate happens after the stall.

Fixes KHR-GL43.copy_image.functional which does a CopyImage (blorp_copy)
from a buffer (using R8G8B8A8_UINT), then GetTexImage to read back the
original image (using R10G10B10A2_UNORM).
