76acefd831 After loading cache mark used core ids. 
Since OCF doesn't use core and cache ids anymore adapter has to track occupied
ids on its own. After loading cache, ids of all loaded cores should be marked as
occupied, otherwise adding new core without explicit specifying core id will
fail.

95af3c6f9f Move to blk-mq block interface. 
Currently Open-CAS uses single queue block interface,
which is removed in kernel in version 5.0.
From this moment on Open-CAS supports only blk-mq,
and single queue is not supported any longer.

202da8140c Additional data type ops: deinit. 
While unloading cas_cache module, volume types were deinitialized, although core
pool still wasn't empty. Now this deinitialization can be done after removing
cores from core pool, and before context is freed.
