    drm/syncobj: Add a fast path to drm_syncobj_array_find
    
    Running the Cyberpunk 2077 benchmark we can observe that the lookup helper
    is relatively hot, but the 97% of the calls are for a single object. (~3%
    for two points, and never more than three points. While a more trivial
    workload like vkmark under Plasma is even more skewed to single point
    lookups.)
    
    Therefore lets add a fast path to bypass the kmalloc_array/kfree and use a
    pre-allocated stack array for those cases.
