drm/i915: Unbind all vmas whose new cache_level doesn't agree with the neighbours

Browse source

When we change the cache_level for an object we need to make sure
we don't put differing types of snoopable memory too close to each
other on non-LLC machines.

Currently i915_gem_object_set_cache_level() will stop looking when
it finds just one vma that has such a conflict. Drop the bogus break
statement to make sure it will unbind all vmas which need to be moved
around to avoid the conflict.

I suppose this is a theoretical issue as currently we don't enable
ppgtt on non-LLC machines, so each object can only have one vma.
