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.
