hw/nvram/fw_cfg: Simplify fw_cfg_add_from_generator() error propagation
Document FWCfgDataGeneratorClass::get_data() return NULL on error, and non-NULL on success. This allow us to simplify fw_cfg_add_from_generator(). Since we don't need a local variable to propagate the error, we can remove the ERRP_GUARD() macro.
