    drm/xe/bo: sync kernel fences for KMD buffers
    
    With things like pipelined evictions, VRAM pages can be marked as free
    and yet still have some active kernel fences, with the idea that the
    next caller to allocate the memory will respect them. However it looks
    like we are missing synchronisation for KMD internal buffers, like
    page-tables, lrc etc. For userspace objects we should already have the
    required synchronisation for CPU access via the fault handler, and
    likewise for GPU access when vm_binding them.
    
    To fix this synchronise against any kernel fences for all KMD objects at
    creation. This should resolve some severe corruption seen during
    evictions.
    
    v2 (Matt B):
      - Revamp the comment explaining this. Also mention why USAGE_KERNEL is
        correct here.
    v3 (Thomas):
      - Make sure to use ctx.interruptible for the wait.
