backends/cryptodev: Do not ignore throttle/backends Errors
Both cryptodev_backend_set_throttle() and CryptoDevBackendClass::init()
can set their Error** argument. Do not ignore them, return early
on failure. Without that, running into another failure trips
error_setv()'s assertion. Use the ERRP_GUARD() macro as suggested
in commit ae7c80a7bd ("error: New macro ERRP_GUARD()").
