be2net: Extend xmit workaround to BE3 chip 



We have seen a bug where the NIC incorrectly changes the length in the
IP header of a padded packet to include the padding bytes. The driver
already has a workaround for this so do the workaround for this NIC too.
This resolves the issue.

The NIC in question identifies itself as follows:

[    8.828494] be2net 0000:02:00.0: FW version is 10.7.110.31
[    8.834759] be2net 0000:02:00.0: Emulex OneConnect(be3): PF FLEX10 port 1

02:00.0 Ethernet controller: Emulex Corporation OneConnect 10Gb NIC (be3) (rev 01)

Fixes: ca34fe38 ("be2net: fix wrong usage of adapter->generation")
