crypto: qat - use struct_size() helper
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct qat_alg_buf_list {
...
struct qat_alg_buf bufers[];
} __packed __aligned(64);
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
So, replace the following form:
sizeof(struct qat_alg_buf_list) + ((1 + n) * sizeof(struct qat_alg_buf))
with:
struct_size(bufl, bufers, n + 1)
