crypto: ccp - Ignore unconfigured CCP device on suspend/resume
commit 5871cd93 upstream. If a CCP is unconfigured (e.g. there are no available queues) then there will be no data structures allocated for the device. Thus, we must check for validity of a pointer before trying to access structure members.
