net/mlx5: add GENEVE TLV option flow validation

This patch adds validation routine for the GENEVE
header TLV option.

The GENEVE TLV option match must include all fields
with full masks due to NIC does not support masking
on option class, type and length.

The option data length must be non zero and provided
data pattern should be zero neither due to hardware
limitations.
