Description
After starting sync, restarting a gateway with a different value of rgw_md_log_max_shards or rgw_data_log_num_shards can cause a segmentation fault.
Radosgw should only consult these values if it has not yet initialized its sync status. Furthermore, rgw_md_log_max_shards should only be consulted by the metadata master zone, and all other zones should query that value from the metadata master when initializing its mdlog sync status.
