drm/amdgpu: properly account for resets with user queues

Browse source

We need to increment the reset counter, force fence completion,
and set the wedged event when a user queue is reset, but only
for the guilty queue.  We don't want additional events for
collateral damage.

Only increment the reset counter and set the wedged event
in the top level userq reset callers (both KGD and KFD).
This aligns with how this is managed for kernel queue resets.

v2: fix task info refcount handling, align with
    kfd error reporting.
v3: check for has_reset_queue in KFD path (Prike)
