drm/amdkfd: Free gang_ctx_bo and wptr_bo in pqm_uninit

Browse source 
[ Upstream commit 72838777aa38352e20301e123b97110c456cd38e ]

[Why]
Memory leaks of gang_ctx_bo and wptr_bo.

[How]
Free gang_ctx_bo and wptr_bo in pqm_uninit.

v2: add a common function pqm_clean_queue_resource to
free queue's resources.
v3: reset pdd->pqd.num_gws when destorying GWS queue.
