drm/amdkfd: Fix bug in config_dequeue_wait_counts
For certain ASICs where dequeue_wait_count don't need to be initialized,
pm_config_dequeue_wait_counts_v9 return without filling in the packet
information. However, the calling function interprets this as a success
and sends the uninitialized packet to firmware causing hang.
Fix the above bug by not calling pm_config_dequeue_wait_counts_v9 for
ASICs that don't need the value to be initialized.
v2: Removed redudant code.
Tidy up code based on review comments
v3: Don't call pm_config_dequeue_wait_counts_v9 for certain ASICs
Fixes: ed962f8d0603 ("drm/amdkfd: Add pm_config_dequeue_wait_counts API")
