net: xsk: dpaa2: avoid repeatedly updating the global consumer

This patch avoids another update of the consumer at the end of
dpaa2_xsk_tx().

In the zero copy xmit path, two versions (batched and non-batched)
regarding how the consumer of tx ring changes are implemented in
xsk_tx_peek_release_desc_batch() that eventually updates the local
consumer to the global consumer in either of the following call trace:
1) batched mode:
   xsk_tx_peek_release_desc_batch()
       __xskq_cons_release()
2) non-batched mode:
   xsk_tx_peek_release_desc_batch()
       xsk_tx_peek_release_fallback()
           xsk_tx_release()

As we can see, dpaa2_xsk_tx() doesn't need to call extra release function
to handle the sync of consumer itself.
