acpi, nfit: check for the correct event code in notifications
Commit 209851649dc4 "acpi: nfit: Add support for hot-add" added support for _FIT notifications, but it neglected to verify the notification event code matches the one in the ACPI spec for "NFIT Update". Currently there is only one code in the spec, but once additional codes are added, older kernels (without this fix) will misbehave by assuming all event notifications are for an NFIT Update.
