Subject: drm/amdkfd: wait only for IH work on IH exit
Git-commit: 0f875e3f3e422d28bb80757269837def75009778
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
We don't need to wait for all work to complete in the IH exit function.
We only need to make sure the interrupt_work has finished executing to
guarantee that ih_kfifo is no longer in use.
