cef13315d0 Compare properties of a new cache device during cache attach 
New cache device must have all the same properties then the previously
attached one.
Keeping cache properties in cache priv also allows to add new cores to
detached cache instance.

4c431bf71c Return error on cache mode change in standby mode 
Changing cache mode to the same mode is a special case that in OCL is
handled on the kernel level, without calling an OCF API. In result it
seemed to succeed even in standby mode, which should return an error.

Explicitly check for standby to return an appropriate error code.

d9d8062f7c Mark cache priv as inited during activate 
Cache priv is being allocated on starting cache instance and is freed only when
stopping cache. This cachnge allows to properly handle rollback if activate has
failed. Without setting this flag managment queue is not being stopped despite
its cache doesn't exist.

05e0590fbc Protect core config preparation function against non-existing cache 
It is legal to call KCAS_IOCTL_INSERT_CORE against non-existing cache
(in try_add mode), however in that case core_id has to be provded.
Return error code in case when given cache id does not exist and core_id
is set to OCF_CORE_MAX.
