[net PATCH] octeontx2-pf: Do not use HW TSO when gso_size < 16bytes

[Geetha sowjanya]

Hardware doesn't support packet segmentation when segment size
is < 16 bytes. Hence add an additional check and use SW 
segmentation in such case.

Fixes: 86d7476078b8 ("octeontx2-pf: TCP segmentation offload support").
