Steve Yang 5dfbad550c net/cxgbe: fix jumbo frame flag condition
The jumbo frame uses the 'RTE_ETHER_MAX_LEN' as boundary condition.
If the Ether overhead is larger than 18 when it supports VLAN tag,
that will cause the jumbo flag rx offload is wrong when MTU size is
'RTE_ETHER_MTU'.

This fix will normalize the boundary condition with 'RTE_ETHER_MTU'
and overhead even though current overhead is 18.

Fixes: 4b2eff452d2e ("cxgbe: enable jumbo frames")
Fixes: 0ec33be4c857 ("cxgbe: allow to change mtu")
