drm/amdgpu: add timeout flush mechanism to update wptr for self interrupt (v2)
outstanding log reaches threshold will trigger IH ring1/2's wptr
reported, that will avoid generating interrupts to ring0 too frequent.
But if ring1/2's wptr hasn't been increased for a long time, the outstanding log
can't reach threshold so that driver can't get latest wptr info and
miss some interrupts.
v2: squash in warning fix
