Tighten the CPER protocol error kfifo registration API and symbol visibility. Use EXPORT_SYMBOL_FOR_MODULES() instead of EXPORT_SYMBOL_NS_GPL() for the CPER kfifo registration symbols. This names the consuming module explicitly and gives compile-time enforcement. Drop the work_struct argument from the unregister path. Change the WARN_ONCE condition to a NULL check since there is no caller pointer to compare against anymore. Return void from the registration helpers whose result callers ignore. cxl_cper_register_work() keeps its int return as the only one consumed by a caller. Flag double registration with WARN_ONCE() inside the lock instead of returning an error. Change cxl_ras_init() to void because there is one consumer and one producer so the error return was unnecessary. Remove the now-dead error check in cxl_core_init().
