dpdk: show hardware may display the wrong information for rss active

Some dpdk driver does not support rte_eth_dev_rss_hash_conf_get. When that
happens, we display whatever that was in the stack variable for rss_hf which
is confusing.

The fix is to clear rss_hf prior to the call.

ipsec: fix support check when using AES-GCM

When adding an IPsec SA, ipsec_check_support_cb() is called. This
invokes a callback for AH and a callback for ESP to check if the
algorithms are supported.

When using AES-GCM on an ESP SA with the DPDK IPsec backend selected,
the AH callback fails. The DPDK IPsec backend has no AH support,
so the callback for the default OpenSSL backend is invoked. This
checks whether the crypto algorithm is AES-GCM and returns failure.

Only invoke the callback to check support for the IPsec protocol
of the SA - either AH or ESP rather than doing both.
