drm/amdgpu: Increase KIQ invalidate_tlbs timeout
KIQ invalidate_tlbs request has been seen to marginally exceed the
configured 100 ms timeout on systems under load.
All other KIQ requests in the driver use a 10 second timeout. Use a
similar timeout implementation on the invalidate_tlbs path.
v2: Poll once before msleep
v3: Fix return value
