Propagate this to callers so they can know if a map is\nabout to be deleted.\n\nFixes this warning:\nrefcount_t: addition on 0; use-after-free.\nWARNING: CPU: 5 PID: 10100 at lib/refcount.c:25 refcount_warn_saturate\n...\nCall trace:\n refcount_warn_saturate\n [fastrpc_map_get inlined]\n [fastrpc_map_lookup inlined]\n fastrpc_map_create\n fastrpc_internal_invoke\n fastrpc_device_ioctl\n __arm64_sys_ioctl\n invoke_syscall",
