Set core_id during load if user did not specify one

Browse Source 
If cfg->core_id is OCF_CORE_MAX and that core matches the UUID of
existing not opened one, then set cfg->core_id to id of that core.

This is useful when loading cache from metadata: if user does not store
the ids of cores but relies on OCF to assign them, there is no need to
not reassign them on load.

Previus behaviur when cfg->core_id != id of core with matching UUID is
maintained.
