ACPI: NFIT: Fix incorrect calculation of idt sizelibnvdimm-fixes-6.6-rc5libnvdimm-fixes
acpi_nfit_interleave's field 'line_offset' is switched to flexible array [1],
but sizeof_idt() still calculates the size in the form of 1-element array.
Therefore, fix incorrect calculation in sizeof_idt().

Fixes: 2a5ab99847bd ("ACPICA: struct acpi_nfit_interleave: Replace 1-element array with flexible array")
