crypto/ipsec_mb: fix cipher key setting

When authenticating with SNOW3G, KASUMI and ZUC,
the pointers for encryption/decryption keys is not set.
If a cipher algorithm such as AES-CBC is also used,
the application would seg fault.
Hence, these pointers should be set to some value by default.

Command line to replicate the issue:
./build/app/dpdk-test-crypto-perf -l 4,5 -n 6 --vdev="crypto_aesni_mb" -- \
 --devtype="crypto_aesni_mb" --optype=cipher-then-auth --auth-algo \
 snow3g-uia2 --auth-key-sz 16 --auth-iv-sz 16 --digest-sz 4 --silent \
 --total-ops 1000000 --auth-op generate --burst-sz 32 \
 --cipher-algo aes-ctr --cipher-key-sz 16 --cipher-iv-sz 16
