[PATCH v4 07/27] net/i40e: use proper flex len define

For FDIR, we have byte arrays that are supposed to be limited to whatever
the HW supports in terms of flex descriptor matching. However, in the
structure definition, spec and mask bytes are using different array length
defines, and the only reason why this works is because they evaluate to the
same value.

Use the i40e-specific definition instead.
