Since there is no kernel-kernel api available to communicate
with nvme driver it is more convenient to use some nvme-dedicated
software (e.g. nvme-cli) to manage nvme devices.
It is even not possible to format nvme device with CAS using current
implementation on newest kernels.

struct ocf_mngt_core_config no longer contains this information,
so we need to pass it as separate argument.

This needs to be done in caller application context. As part of asynchronous
management API rework, volume_open callback was moved to kernel worker thread
context. To work around this, atomic parameters are now read before cache
attach/load/probe and provided to bottom volume via volume params.
