[PATCH] net/i40e: avx512 fast-free path bug fix

[Kamalakshitha Aligeri]

In i40e_tx_free_bufs_avx512 fast-free path, when cache is NULL,
non fast-free path is being executed. Fixed the bug by calling
rte_mempool_generic_put API that handles the cache==NULL case.

Fixes: 5171b4ee6b6b ("net/i40e: optimize Tx by using AVX512")
