crypto: qat - Use static_assert() to check struct sizes
Commit 140e4c85d540 ("crypto: qat - Avoid -Wflex-array-member-not-at-end
warnings") introduced tagged `struct qat_alg_buf_list_hdr`. We want to
ensure that when new members need to be added to the flexible structure,
they are always included within this tagged struct.
So, we use `static_assert()` to ensure that the memory layout for
both the flexible structure and the tagged struct is the same after
any changes.
