crypto: ccp - Ignore unconfigured CCP device on suspend/resume
commit 5871cd93692c8071fb9358daccb715b5081316ac 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.
