Capability information is updated as slaves are attached,
but if this information is requested via rte_cryptodev_info_get()
when no slaves have been attached, the structure would not be
initialized, leading to a potential segmentation fault.
Therefore, the structure should be initialized with no
capabilities at device creation.
