    drm/i915: Move tasklet kicking to __i915_request_queue caller

    Since __i915_request_queue() may be called from hardirq (timer) context,
    we cannot use local_bh_disable/enable at the lower level. As we do want
    to kick the tasklet to speed up initial submission or preemption for
    normal client submission, lift it to the normal process context
    callpath.
