drm/amdkfd: Fix CRIU restore op due to doorbell offset

Recently introduced change to allocate doorbells only when the first
queue is created or mapped for CPU / GPU access, did not consider
Checkpoint Restore scenario completely. This fix allows the CRIU restore
operation by extending the doorbell optimization to CRIU restore
scenario.

Fixes: 16f0013157bf ("drm/amdkfd: Allocate doorbells only when needed")
