drm/amdgpu: Increase tlb flush timeout for sriov
[Why]
During multi-vf executing benchmark (Luxmark) observed kiq error timeout.
It happenes because all of VFs do the tlb invalidation at the same time.
Although each VF has the invalidate register set, from hardware side
the invalidate requests are queue to execute.
[How]
In case of 12 VF increase timeout on 12*100ms
