net/ixgbe: remove unnecessary macro

Browse Source 
Since we move to new offload APIs, IXGBE_SIMPLE_FLAGS is not used.

Fixes: 51215925a32f ("net/ixgbe: convert to new Tx offloads API")

Feature not Supported by TX Vector PMD
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TX vPMD only works when txq_flags is set to IXGBE_SIMPLE_FLAGS.
TX vPMD only works when offloads is set to 0
This means that it does not support TX multi-segment, VLAN offload and TX csum offload.
The following MACROs are used for these three features:
* ETH_TXQ_FLAGS_NOMULTSEGS
* ETH_TXQ_FLAGS_NOVLANOFFL
* ETH_TXQ_FLAGS_NOXSUMSCTP
* ETH_TXQ_FLAGS_NOXSUMUDP
* ETH_TXQ_FLAGS_NOXSUMTCP
This means that it does not support any TX offload.
