The SA salt of struct ipsec_sa is a CPU-endian u32 variable, but it’s
value is stored in an array of encryption or authentication keys
according to big-endian. So it maybe need to convert the endianness
order to ensure that the value assigned to the SA salt is CPU-endian.

Fixes: 50d75cae2a2c ("examples/ipsec-secgw: initialize SA salt")
Fixes: 9413c3901f31 ("examples/ipsec-secgw: support additional algorithms")
Fixes: 501e9c226adf ("examples/ipsec-secgw: add AEAD parameters")

The patch is pulled back from dpdk-next-crypto.
This change may cause all the PMDs to fail these cases.
Would need acks from PMDs.
