zram: move immutable comp params away from per-CPU context
Immutable params never change once comp has been allocated and setup, so
we don't need to store multiple copies of them in each per-CPU backend
context. Move those to per-comp zcomp_params and pass it to backends
callbacks for requests execution. Basically, this means parameters
sharing between different contexts.
Also introduce two new backends callbacks: setup_params() and
release_params(). First, we need to validate params in a driver-specific
way; second, driver may want to allocate its specific representation of
the params which is needed to execute requests.
