cls_rgw_gc_queue_list_entries() reads the urgent data map at the beginning as part of read_queue_head(). but if urgent_data.num_xattr_urgent_entries > 0, we call cls_cxx_getxattr(hctx, "cls_queue_urgent_data", &bl_xattrs) for each gc queue entry that isn't in the urgent_data map to check for it in xattr_urgent_data_map

we should read the "cls_queue_urgent_data" xattr (if urgent_data.num_xattr_urgent_entries > 0) at the beginning of cls_rgw_gc_queue_list_entries() to avoid re-reading it for each entry
