6.5-stable review patch. If anyone has any objections, please let me know.

From: Yu Liao liaoyu15@huawei.com
commit 33908660e814203e996f6e775d033c5c32fcf9a7 upstream.
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().
