cryptodev: Account statistics

Account OPS/BPS for crypto device, this will be used for 'query-stats'
QEMU monitor command and QoS in the next step.

Note that a crypto device may support symmetric mode, asymmetric mode,
both symmetric and asymmetric mode. So we use two structure to
describe the statistics of a crypto device.
