[PATCH] drm/amdgpu: put ctx's ref count in amdgpu_ctx_mgr_entity_fini()

[Lin . Cao]

patch "daf823f1d0cd drm/amdgpu: Remove duplicated "context still
alive" check" removed ctx put, which will cause amdgpu_ctx_fini()
cannot be called and then cause some finished fence that added by
amdgpu_ctx_add_fence() cannot be released and cause memleak.
