[PATCH 16/17] drm/amdkfd: wait only for IH work on IH exit

From: Andres Rodriguez <andres.rodriguez at amd.com>

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.
