bonding: Add ESN support to IPSec HW offload

Browse Source 
Currently, users can see that bonding supports IPSec HW offload via ethtool.
However, this functionality does not work with NICs like Mellanox cards when
ESN (Extended Sequence Numbers) is enabled, as ESN functions are not yet
supported. This patch adds ESN support to the bonding IPSec device offload,
ensuring proper functionality with NICs that support ESN.
