[PATCH] drm/amdgpu: increase timeout of IB test

[Christian König]

Ok, I really wasn't expecting this. How about 100ms?

I just want to avoid that a reset takes more than 1 or 2 seconds even 
when it didn't worked.

With 1 second timeout for each IB test we easily need 10+ seconds when 
the hardware doesn't response at all.

Regards,
Christian.
