i40iw: Fix sequence number for the first partial FPDU

i40iw: Fix sequence number for the first partial FPDU

[ Upstream commit df8b13a1b23356d01dfc4647a5629cdb0f4ce566 ]

Partial FPDU processing is broken as the sequence number
for the first partial FPDU is wrong due to incorrect
Q2 buffer offset. The offset should be 64 rather than 16.
