From: Qiming Chen <chenqiming_huawei at 163.com>

In the eth_i40e_dev_init function, the tunnel and ehtertype hash table
resource release interface should be rte_hash_free instead of rte_free,
and the previously registered interrupt handling function also needs to
be removed from the interrupt list. The patch is amended to use the
correct interface to release the hash table resource and release the
interrupt handling function at the same time.

Fixes: 425c3325f0b0 ("net/i40e: store tunnel filter")
5c53c82c8174 ("net/i40e: store flow director filter")
