	module_is_live function is only defined when CONFIG_MODULES is enabled. Use try_module_get instead to check whether the module is being removed. When module unload and manuall unmapping is happening in parallel, we can try removing the symlink twice: rnbd_client_exit vs. rnbd_clt_unmap_dev_store. This is probably not the best way to deal with this race in general, but for now this fixes the compilation issue when CONFIG_MODULES is disabled and has no functional impact. Regression tests passed.
