[PATCH] drm/xe/display: fix i915_gem_object_is_shmem() wrapper

[Kandpal, Suraj]

> 
> shmem ensures the memory is cleared on allocation, however here we are
> using TTM, which doesn't natively support shmem (other than for swap), but
> instead just allocates normal system memory. And we only zero such memory
> for userspace allocations. In the case of intel_fbdev we are missing the
> memset_io().
