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.

I gave you Reviewed-by, not Signed-off-by.

Before you send more patches, read this:

Documentation/process/submitting-patches.rst

You can read the whole document but do especially concentrate on
sections 11-13, in order to get an idea how the SOB chain and all that
patch tagging works.

Thx.
