drm/amdgpu: Increase KIQ invalidate_tlbs timeout

Browse source

[ Upstream commit 3666ed8218 ]

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
