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.
