[PATCH V2] drm/amdgpu: make compute timeouts consistent

For kernel compute queues, align the timeout with
other kernel queues (10 sec).  This had previously
been set higher for OpenCL when it used kernel
queues, but now OpenCL uses KFD user queues which
don't have a timeout limitation. This also aligns
with SR-IOV which already used a shorter timeout.

Additionally the longer timeout negatively impacts
the user experience with kernel queues for interactive
applications.
