ACPI / APEI: remove the unused dead-code for SEA/NMI notification type
For the SEA notification, the two functions ghes_sea_add() and ghes_sea_remove() are only called when CONFIG_ACPI_APEI_SEA is defined. If not, it will return errors in the ghes_probe() and not continue. If the probe is failed, the ghes_sea_remove() also has no chance to be called. Hence, remove the unnecessary handling when CONFIG_ACPI_APEI_SEA is not defined. For the NMI notification, it has the same issue as SEA notification, so also remove the unused dead-code for it.
