kfd process check in switch partition\n\ncurrent switch partition only check if kfd_processes_table is empty.\nkfd_prcesses_table entry is deleted in kfd_process_notifier_release, but\nkfd_process tear down is in kfd_process_wq_release.\n\nconsider two processes:\n\nProcess A (workqueue) -> kfd_process_wq_release -> Access kfd_node member\nProcess B switch partition -> amdgpu_xcp_pre_partition_switch -> amdgpu_amdkfd_device_fini_sw\n-> kfd_node tear down.\n\nProcess A and B may trigger a race as shown in dmesg log.\n\nThis patch is to resolve the race by adding an atomic kfd_process counter\nkfd_processes_count, it increment as create kfd process, decrement as\nfinish kfd_process_wq_release.\n\nv2: Put kfd_processes_count per kfd_dev, move decrement to kfd_process_destroy_pdds\nand bug fix.
