Drop cpu_dirty_logging_count in favor of nr_memslots_dirty_logging. Both fields count the number of memslots that have dirty-logging enabled, with the only difference being that cpu_dirty_logging_count is only incremented when using PML. So while nr_memslots_dirty_logging is not a direct replacement for cpu_dirty_logging_count, it can be combined with enable_pml to get the same information.
