drm/amdkfd: Refactor queue wptr_bo GART mapping
Add helper function kfd_queue_acquire_buffers to get queue wptr_bo reference from queue write_ptr if it is mapped to the KFD node with expected size. Add wptr_bo to structure queue_properties because structure queue is allocated after queue buffers are validated, then we can remove wptr_bo parameter from pqm_create_queue. Rename structure queue wptr_bo_gart to hold wptr_bo reference for GART mapping and umapping. Move MES wptr_bo_gart mapping to init_user_queue, the same location with queue ctx_bo GART mapping.
