drm/i915: Remove redundant TLB invalidate on switching ppgtt

Browse source

We are required to reload the TLBs around ppgtt switches. However, we
already do an unconditional TLB invalidate before every batch and a flush
afterwards, so this condition is already satisfied without extra flushes
around the LRI instructions.
