drm/gpu: Remove dead checks on wbinvd_on_all_cpus()'s return value

Browse Source 
Remove the checks and associated pr_err() on wbinvd_on_all_cpus() failure,
as the helper has unconditionally returned 0/success since commit

  caa759323c ("smp: Remove smp_call_function() and on_each_cpu() return values").
