[dpdk-dev] [v2] test: fix crypto_op length for sessionless case

[Abhinandan Gujjar]

Currently, private_data_offset for the sessionless is computed
wrongly which includes extra bytes added by
sizeof(struct rte_crypto_sym_xform) * 2. This causes buffer
overflow which leads to test application crash while freeing the
ops mempool. This patch provides fix for the same and also takes
care of increasing the length of ops to accommodate space for
rte_event_crypto_metadata while creating the crypto ops mempool.

Fixes: 3c2c535ecfc0 ("test: add event crypto adapter auto-test")

v2:
 - Fix length calculation for copying metadata
 - Update mempool's size to accommodate space for metadata
