test/event_crypto: fix event crypto metadata write

  Using memcpy to update event crypto metadata fields (request/response)
will result in one overwriting the other. To avoid this, fields of each
structure should be updated one by one.

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