Don't assert mips actually need resolve during texResolveRenderTask

Too many exceptions can arise during flush in which the mips won't
actually be marked dirty: Failed to flush GL state, Ops that don't
actually issue any draws, etc. Since the DAG can't and shouldn't
predict these rare exceptions, we just remove the assert.
